BREAKDOWN IN SOLID DIELECTRIC The requirements of good dielectric: o Low dielectric loss‚ o High mechanical strength‚ o Free from gaseous inclusions‚ and moisture‚ o Resistant to thermal and chemical deterioration. Solid dielectrics have higher breakdown strength compared to liquids and gases. When breakdown occurs‚ solids get permanently damaged while gases fully and liquids partly recover their dielectric strength. Breakdown mechanism varies depending

Google Glass: Wearable Technology to the Next Level Abstract Google glass is a type of wearable technology with an optical head-mounted display (OHMD). It was developed by Google with a goal of producing mass-market ubiquitous computers. It looks like a pair of eyeglasses‚ except‚ the lens of the Google glass is a user-interactive display and supports Wi-Fi and Bluetooth connectivity. It was primarily designed to take phone calls‚ send texts‚ take photos and videos and deliver search results.

combined in any imaginable configuration. The MEMS Module includes analyses in the stationary and transient domains as well as fully-coupled eigenfrequency‚ parametric‚ quasi-static‚ and frequency response analyses. Lumped parameter extraction of capacitance‚ impedance‚ and admittance and connections to external electrical circuits via SPICE netlists are made easy. Built upon the core capabilities ofCOMSOL Multiphysics‚ the MEMS Module can be used to address virtually any phenomena related to mechanics

RC Circuits •In this presentation‚ circuits with multiple batteries‚ resistors and capacitors will be reduced to an equivalent system with a single battery‚ a single resistor‚ and a single capacitor. Kirchoff ’s laws will be stated‚ and used to find the currents in a circuit. In addition‚ the equation for the time-constant of an RC circuit will be derived. Ohm ’s Law When a battery is connected to a resistor‚ the battery will cause a current to flow through the resistor. The larger the voltage

difference of the Voltage controlled oscillator (VCO) from the other oscillator types is the oscillation frequency can be determined by the Vcont voltage. The variable capacitor (varactor) plays the main role here‚ if the Vcont changes than the capacitance of the varactor changes and this eventually changes the oscillation frequency. There are some crucial points that require attention while designing an oscillator: Stability‚ Phase Noise‚ Gain‚ Q factor‚ Frequency Pushing and Pulling. In this report

The optimal M1‚2 width (W) is determined for several M1‚2 lengths (L) and bias current Ibias‚ and the overall optimal set of values is W=600µm‚ L=3µm‚ Ibias=53µA. Noise measurements show that 1/f noise has a slightly higher impact than does white noise‚ when both contributions are A-weighted. The expected SNR degradation introduced
