Circuit operating as nonlinear twin terminal network - has differential amplifier with nonlinear component in feedback circuit

摘要

The circuit characteristic has a threshold, and the circuit comprises an operational amplifier and a nonlinear component with threshold characteristic. It is connected to a reference voltage. The circuit (Z1) has a differential amplifier (OD) with the nonlinear component (D) in the feed-back circuit (1) to an input (2), which is one of the network two terminals (2a, 2b). The other input (3) is for the reference voltage (Ur1) source (4). The twin terminal circuit (22) has similar components; the system may be extended to more than two branches.
