ABSTRACT:
A circuit formed with an input stage (20) and an output stage (22 or 28) uses capacitively enhanced switching to improve switching speed without significantly raising steady-state current utilization. The output stage contains a pair of amplifiers (A1and A2) that respond to complementary signals (V.sub.M1 and V.sub.M2) produced by the input stage. The amplifiers are coupled to a pair of corresponding nodes (N1 and N2). A third amplifier (A3) in the output stage has a control electrode coupled to one of the nodes, a flow electrode coupled to the other node, and another flow electrode coupled to a further node (N3). A current supply (24) provides current at the further node. A charge/discharge element (CD1) produces a capacitive-type charge/discharge action between the further node and a source of a reference voltage (V.sub.R1). The output stage may also include a fourth amplifier (A4), another current supply (26), and another such charge/discharge element (CD2) arranged in a complementary manner to the three preceding components.
