MT-027: ADC Architectures VIII: Integrating ADCs by Walt Kester and James Bryant Rev. 0‚ 02-13-06 INTRODUCTION Soon after the discovery of the basic counting ADC architectures (see Tutorial MT-026) it was realized that much greater accuracy could be obtained using a combination of integrating and counting techniques. This led to the development of high accuracy dual-slope‚ triple-slope‚ and quad-slope ADCs. Although the proliferation of high resolution sigma-delta ADCs has made integrating

DAC(digital-to-analog converter) In electronics‚ a digital-to-analog converter (DAC or D-to-A) is a device that converts a digital (usually binary) code to an analog signal (current‚ voltage‚ or electric charge). An analog-to-digital converter (ADC) performs the reverse operation. Signals are easily stored and transmitted in digital form‚ but a DAC is needed for the signal to be recognized by human senses or other non-digital systems. A common use of digital-to-analog converters is generation of audio

executed every 8ms. Develop a method to verify the timing of that routine‚ e.g.‚ increment LEDs. 3. Program the A/D converter to read the value from the pot either the one on the microcontroller board or an external one. In the routine developed in Part 1‚ read the A/D converter (use 8-bit mode). Again develop a method to display the results and verify the operation of the A/D converter as you change the input voltage. 4. Set up the PWM to generate a 50 kHz PWM signal on one of the four PWM channels

Project Synopsis ECE 441 HDL Programming Topic: Analog to Digital Converter using Verilog programming Language By: Kamaalbir Singh (Section: E3901‚ Roll No: B28) & Jasmeet Singh (Section: E3901‚ Roll No: B27) Introduction: An analog-to-digital converter (ADC) is a device that converts a continuous physical quantity (usually voltage) to a digital number that represents the quantity’s amplitude. The conversion involves quantization of the input‚ so it necessarily introduces a small
