Abstract

1,016,975. Transistor gating and amplifying circuits. GEORGE KENT Ltd. Oct. 5, 1964 [Oct 7, 1963], No. 39474/63. Heading H3T. In a gating or chopping circuit employing a field-effect transistor, the effect of leakage current in the transistor is minimized by means of a compensating voltage applied over a path including a reverse-connected semi-conductor diode having a leakage current/temperature characteristic equivalent to that of the transistor. The compensating planar diode may have a leakage current identical to that of the field effect transistor employed as a chopper in a modulator/demodulator amplifier and may be supplied with the inverse chopping waveform. Alternatively, a diode having a leakage current greater than that of the field effect transistor may be employed by reducing the compensating voltage or by shunting the compensating current.
