Impatt Diode Working: IMPATT Diode Working is a combination of delay involved in generating avalanche current multiplication, together with delay due to transit time through a drift space, provides the…
Gunn Effect: In 1963, Gunn discovered the transferred electron effect which now bears his name. This Gunn Effect is instrumental in the generation of microwave oscillations in bulk semiconÂductor materials.…
Microwave Transistors: Silicon bipolar transistors were first on the microwave scene, followed by GaAs field-effect transistors. Indeed, FETs now have noticeably lower noise figures, and in the C band and…
Planar Triode Construction: Planar Triode Construction - A short transit time is essential if grid loss and noise are to be minimized, as is the reduction of internal capacitances and…
Generation of Amplitude Modulation: There are two types of devices in which it may be necessary to the Generation of Amplitude Modulation. The first of these, the AM transmitter, generates…
Transistor Buffer Circuit: The Fig. 15.12 shows the Transistor Buffer Circuit. In these Transistor Buffer Circuit, transistor is used as a switch. It can be switch ON or OFF with…
