ABSTRACT:
Bidirectional amplifier employs a single buffer amplifier (64). The bidirectional amplifier is programmed by applying a control signal (Q) and its complementary signal (Q), which establishes the state of four pass transistors (P'.sub.1, P'.sub.2, P'.sub.3, P'.sub.4) or four CMOS transmission gates (T.sub.1, T.sub.2, T.sub.3, T.sub.4). For a first selection of the control signal, the bidirectional amplifier receives an input signal on a first lead (A') and produces an amplified signal on a second lead (B'). For a second selection of the control signal, the amplifier receives an input signal on the second lead (B') and produces an amplified output signal on the first lead (A').
