The CCG (current-controlled gate) circuits of Figs. 1A and 1B, with which the disclosed switchable bypass network may be employed, are fully disclosed and described in [*]. The bypass network extends the push-pull operation of the CCG circuit to 100-microwatt power range. The use of the switchable bypass network provides (1) a high enough base-to-collector current to develop adequate coupling capacitance and (2) a return of the collector of T3 to a low enough voltage so that T5 is effectively held off. Referring to Figs. 1A and 1B, the reference 1 describes the operation of the CCG circuit and the DC biasing requirement of T3 to keep T5 at low current when the output is in the high state.
