Unit 1 Research Assignment 1: Integrated Circuit Technology An integrated circuit is a tiny complex of electronic components and their connections that are produced in or on a small slice of material. A MOSFET‚ (Metal Oxide Semiconductor Field Effect Transistor)‚ is the type of transistor used in modern computers. In the most basic form they are an amplifier. They typically have three pins - a source‚ a drain‚ and a gate. When there is voltage (not current) on the gate then the MOSFET

Advantages of Digital Circuits Name: Instructor: Institution: Introduction Digital circuits are circuits that use signals in digital form instead of analog forms. One distinctive feature of a digital signal is that it assumes discrete values‚ most of the time two values. A digital signal takes time to change from one value to another‚ and assumes intermediate values during transmission (Verma). Steady values are slightly inaccurate. Voltages

An Earth Leakage Circuit Breaker (ELCB) (now referred to as residual current circuit breaker) is a safety device used in electrical installations with high earth impedance to prevent shock. History ELCBs were mainly used on TT earthing systems. Nowadays‚ ELCBs have been mostly replaced by residual-current devices (RCDs). However many ELCBs are still in use. Early ELCBs responded to sine wave fault currents‚ but not to rectified fault current. Over time‚ filtering against nuisance trips has also

5. Operational Amplifiers Introduction In many electronic circuits‚ the signals (voltage differences) that are generated and manipulated are very small. Therefore‚ amplification is often essential. When playing a CD for instance‚ the signals generated in the CD player are quite small and will not adequately drive a speaker system. The signals from the CD player are therefore passed into the stereo amplifier (which often comes as a tuner/amplifier combination in modern home stereo systems)
