William S. Carter ABSTRACT, Bidirectional amplifier employs a single buffer amplifier (64). The bidirectional amplifier is programmed by applying a control signal (Q) and its complementary signal (?), which establishes the state of four pass transistors (P?, P?, P?, P?) or four CMOS transmission gates (T1, T2, T3, T4). 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').
