ABSTRACT:
A transistor in which the emitter terminal is coupled to ground through a filter capacitor. The filter capacitor has a capacitance of from about 0.2 .mu.f to about 22 .mu.f and can be connected either by itself or in parallel with a resistor, depending upon the circuit in which it is used. The incorporation of a filter capacitor of such a capacitance level provides greatly improved gain and less distortion of the input signal, to permit a high output to be achieved in fewer amplifier stages and with less current draw and heating than in conventional transistor amplifier stage circuits. Additionally, the transistor can be provided in a unitary structure by incorporating the filter capacitor directly on the transistor chip, and can also be provided by incorporating the transistor and a resistor within the casing of a filter capacitor.
