Abstract
1290011 MOS transistor circuits PLESSEY CO Ltd 6 Feb 1970 [11 Feb 1969] 7252/69 Heading H3T Two MOS T's are connected in series, an input signal is applied to the gate of one and to the gate of the other is applied a fixed potential such that the breakdown voltage between drain and substrate is at least equal to that which it would be with the gate and source on open circuit. It is shown that if the gate is at zero potential the breakdown voltage is less than this. The potential must be at or above a "threshold value" and is negative for p-channel transistors and vice versa. For use in linear A.C. circuits a feedback capacitor 11 may be provided to minimize the input Miller capacitance.
