Abstract

To obtain a constant quiescent current and a symmetrical, counter-phased and stable drive of the FETs (Q1,Q2) from the output to the negative supply the following are connected in series; a bias source (B1) and a resistor (R1), to transistor (Q3), whose control comprises the input or has a constant voltage to the input and a resistor (R2) of the same value as the first (R1). The single control of the FETs normally connected to the emitter of the transistor (Q3) is alternatively coupled to the input of the same transistor, which has approximately the same signal voltage as the emitter.
