Abstract

The signal input is fed to the mid-point of a resistive divider chain (R1 to R4) between the positive and negative supply lines. The other junctions in the divider are connected to the inputs of the two input amplifiers (A1, A2). The outputs of the amplifiers are fed to the commoned bases of complementary pairs of transistors (Q1, Q2 & Q3, Q4). The commoned emitters of each pair are fed via identical resistors to the final output (UIT). The output has a resistive load (RL) and a filter (C3, R7) in parallel.
