Integrated circuits, performance, especially for operational and differential amplifiers. The evolution of ICs based on silicon has been rapid and continuous. Figure 10.1 shows the trend with time in the best . processes for the minimum width of ‘features’ such as conductors, gates and so forth, components/mm. and components/chip, all on a logarithmic scale.

Three-phase systems,mpared to single or two-phase AC systems.. By 1896 the Westinghouse company in the USA had settled exclusively for the three-phase system, partly because it gave smoother motor operation, and very gradually DC systems lapsed into obsolescence.

Operational amplifiers,ics cookbook. When cheap integrated circuits began to appear, the price of op amps (the customary abbreviation for the device) plummeted coincidentally with the increase in performance, so that a high-stability, chopper-stabilised op amp costing £100+ in 1979 may be obtained for less than £5 in 1998

Transients,ry response of a circuit to a change in conditions is required. For example if a power supply in a circuit is switched on there may be a surge, possibly with oscillations, before a steady flow of current is established. One may wish to calculate the magnitude of the transient current to avoid damage

Bode diagrams and 2-port networks, (To some extent any circuit containing reactive components acts as a filter, that is it attenuates more at some frequencies than at others.) Any network may be so arranged as to have a pair of input terminals (the input .) and another pair for output (the output port) as in figure 5.1a. The ratio o

Semiconductors,g germanium (Ge) and silicon (Si) and only silicon is widely used nowadays. However, there are some compound semiconductors which find applications in light-emitting diodes, semiconductor lasers, microwave devices and other specialised areas. Most of these are based on elements from groups III and V
