<p>A transistor (16) in which the emitter terminal is coupled to ground through an electrolytic capacitor (26). The electrolytic capacitor (26) has a capacitance of from about 0.2 νf to about 100 νf and can be connected either by itself or in parallel with a resistor (22) depending upon the circuit in which it is used. The incorporation of an electrolytic 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 (76) can be provided in a unitary structure by incorporating the electrolytic capacitor (86) directly on the transistor chip (76) and can also be provided by incorporating the transistor (88) and a resistor (92) within the casing (90) of an electrolytic capacitor.</p> |
