Abstract :
The principles of transistor amplifier building which can be classified as cascode circuits are observed. The analysis is made on the basis of general structure. And the opportunity to have an increase of amplification in comparison with traditional amplifiers is shown. It is achieved by compensation of collector-base transistor capacitance. The variants of circuit and technological realization of wide-band amplifiers in one of several types of conduction transistors, in functional integrated bipolar and field-effect transistor and in differential cascades, are given.
