Abstract
Active resistive circuitry (10, 10A, 11, 11A 25, 30, 35, or 40) includes a first current divider circuit (11) having an input (15) coupled to a first signal (Vi). The first current divider circuit (11) includes a first amplifier (13) having a first input (−) coupled to the first signal (Vi). A symmetrically bilateral first bidirectional circuit (M1a,M1b; R1) is coupled between the first input (−) of the first amplifier (13) and an output (17) of the first amplifier (13), and functions as a feedback circuit of the first amplifier (13). A symmetrically bilateral second bidirectional circuit (M2a,M2b; R2) is coupled between the output (17) of the first amplifier (13) and an output (18) of the first current divider circuit (11).
