ITCH

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

Diodes,ctify alternating current, some are used as signal detectors and others are used as voltage references or voltage regulators. There are also optical diodes which are used as indicators (light-emitting diodes, or LEDs), signal sources (LEDs and laser diodes) or optical detectors (avalanche photodiode

Bipolar junction transistors,ferent class of device; whereas the diode is a passive device, the transistor is . — it can be used to amplify voltages (signals). The BJT is termed . because its operation — unlike the field effect transistor’s (FET) — depends on both positive (holes) and negative (electrons) charge carriers. Befor

JUST

Field-effect transistors, layer. In the 1970s the problems were solved and FET technology developed at a rapid pace. FETs are now more widely used than BJTs and have made an enormous impact on integrated circuit (IC) technology. Not only have very low-power CMOS (complementary metal oxide-semiconductor, a type of FET) ICs b

小歌剧

ICs and analogue circuits,g together the discrete components of a circuit — such as resistors, capacitors, inductors, diodes and transistors — the IC designer arranges for them to be produced and electrically interconnected as a single ‘chip’. There are many advantages in so doing: the devices need no packaging, the intercon

Power amplifiers and power supplies, to be driven by these was of relatively high impedance resulting in small output power, just as well in view of their low efficiencies. High efficiencies are vital for power amplifiers, not because of the cost of the wasted power itself, but because the wasted power produces heat in the amplifier.
