Amplifier

Abstract From the Canadian patent

An amplifier comprised of a field effect transistor whose gate electrode is adapted to receive an input signal. An impedance converter couples the input signal to the gate electrode of the field effect transistor the impedance con-, verter being formed of n impedance converting stages each, stage having a relatively low output impedance. A voltage limiting circuit is connected between the source of input signal and the gate electrode of the field effect transistor so as to limit the forward biasing of the field effect transistor. This voltage limiting circuit includes m voltagelimiting elements, wherein n and m are integers (1 2, 3, ...), and n is equal to or greater than m. In a preferred …
