Operational Amplifier Applications

Introduction
Operational amplifiers (“op-amp”) are high gain electronic voltage amplifiers, which are the significant building blocks for most electronic circuits. In addition to this, they are still the most widely used microelectronic devices nowadays, being used in vast applications for industrial and individual users. The aim of this experiment is to demonstrate how the operational amplifier operates and show its imperfections via constructing various kind of circuit such as non-inverting/inverting amplifier circuits, filter circuits, differentiator and integrator circuits.

In this report, we will go through two experiments, which are the fundamental circuits of operational amplifiers: non-inverting and inverting amplifier circuits, to analyze the difference between ideal and real op-amps. For the following section, the relevant theory will be introduced, and then the detail and results of the experiments will be discussed before proceeding to conclusion.

Theory

Figure 1 : The op amp and its ideal attributes

As the Figure1 shown, operational amplifier has two inputs labeled (+) and (-) with positive and negative power supply, and a single output. It is primarily a high gain differential amplifier which amplifies the difference of voltages between two inputs. The output voltage of the amplifier Vout is given by the following formula: Vout = A (V+ - V-) --------------- (1)
Where A is the open loop voltages gain of the amplifier, which typically is very large about 105 at low frequency. V+ and V- are the non-inverting and inverting input voltage respectively. From the equation, output voltage is entirely governed by the difference between the two input voltages. However for real op-amps inputs do draw a small amount of current and the output voltage is affected by the output current drawn. For the analysis, both inverting and non-inverting amplifiers are applying negative

    Utilizing the circuit designs perfected for recently introduced Quad Operational Amplifiers, these dual operational amplifiers feature 1) low power drain, 2) a common mode input voltage range extending to ground/VEE, 3) single supply or split supply operation and 4) pinouts compatible with the popular MC1558 dual operational amplifier. The LM158 series is equivalent to one–half of an LM124. These amplifiers have several distinct advantages over standard operational amplifier types in single supply applications. They can operate at supply voltages as low as 3.0 V or as high as 32 V, with quiescent currents about one–fifth of those associated…

    In experiment 2 our main objective was to understand the analysis of resistors, inductors and capacitors in a sine wave circuit. we measured the impedance of the inductor and capacitor using a current sensing resistor. Inductive reactance is the opposition to the flow of current, and capacitive reactance is the opposition to the flow of charge. The tools we used for this experiment a pair of resistors, an inductor, a capacitor, dual channel oscilloscope, audio oscillator, and a digital multimeter. Using the oscilloscope we where able to measure the devises easily. Using the audio oscillator too change our setting to the wright context we measured the Vrms of our circuits. Using the Vrms we were able to find all of our unknowns using equations and our knowledge of circuit analysis.…

    These course notes were originally developed by me for EE476 in Fall 1996 at Washington State University (WSU). The material in these notes has been derived from several sources. These include Dr. Venu Gopinathan's course notes from Columbia University, Dr. David Rich's analog IC design course notes, Prof. Terri Fiez's EE476 course notes, and Prof. Paul Gray's EE240 lecture notes. Their contributions to these notes are gratefully acknowledged. Also a significant amount of the material is based on the Gray and Meyer textbook. Prof. George La Rue at WSU made a monumental effort in cleaning up and formatting the original hand written notes in MS-WORD. I thank him for this effort and for providing me with the formatted notes. This…

    In 2004, Sarah Thomas, an undergraduate student at Portland State University, completed an experiment to determine the effect of biofeedback training on muscle tension and skin temperature. The purpose of this experiment was to train the subject of the experiment to change their decrease muscle tension and increase skin temperatures in response to tones. The experiment was based on the research done by Miller and Bruckner in 1979. The experiment done by Miller and Brucker dealt with how rats can modify their heartbeats when given pleasurable brain stimulation (Lee, 2014). The same premises were used in this experiment to see if humans can adjust their muscle tension and skin temperature as a cause of stimulations. The results found in this lab report claim a correlation between a positive reinforcement and control of one’s body, but these results are invalid due to the low sample size and lack of diversity in…

    When examining stories of competition from the past and present, all of them involve a winner and incontestably, a loser. Sports are the most popular form of competition where people will do almost anything to win, including cheat. Performance enhancing drugs are one of the most talked about issues in sport today. Though many people think that doping has only been an issue for the past 30-40 years, there is evidence of athletes using substances to enhance their performance since the early Olympic games in approximately 700 BC. The testing for substances have always been one step behind the latest drug and many tests for banned substance are not always accurate. This makes it very difficult to catch all of the so-called cheaters. Using banned substances can also have dangerous side effects when not used properly and in the past, many athletes have fallen victim to these problems. Due to the vast list of banned substances in high level sport, many athletes have been stripped of their titles when caught taking something as simple as an over the counter flu medication, which many people feel is not fair. The only solution to these issues in sport is to legalize these banned substances. This would eliminate skepticism, allow athletes to be on the same playing field, and potentially save their lives as they would be properly educated on how to safely take performance enhancing drugs.…

    A signal can be defined as detectable transmitted energy that can be used to carry information. Put in another way, a signal is a time-dependent variation of a characteristic of a physical phenomenon, used to convey information. For example, a signal could be the current flowing through a light dependent resistor (LDR), giving information about the amount of illumination in the LDR's environment. Another signal could be the colour of a methyl orange solution indicating the pH of the solution. Signals discussed in this course will be restricted simply to voltage signals and current signals. Hence, in this course, a signal will be either a voltage or a current.…

    Schematic diagrams are used to graphically represent the components and interconnections of electrical circuits. In the past, schematics were drafted using manual drawing techniques. Up until the late 1970s, the only schematic drafting aids were plastic drawing templates. Back in the late 1970s, CAD (Computer Aided Design) systems based on mainframe and mini-computer technology were just starting to see use in larger companies, but these were very expensive. Simple tasks like routine schematic drafting were difficult to cost justify. But these situations changed with the arrival of the IBM PC and low cost CAD software such as AutoCAD.…
