Frequency dependent resistance simulation circuit for use in e.g. combinatorial circuit device, has connection of impedance connected to output and to connection of controller that is connected to connection of resistance

摘要

The circuit has a controller and an impedance with respective connections (116,117). An input is connected to an output over a controllable resistance and the impedance. The connection (117) of the impedance is connected to the output and to the connection (123) of the controller (120). The connection (121) of the controller is connected to the connection (115) of the controllable resistance. An independent claim is also included for a method of operating or controlling or regulating a frequency dependent resistance simulation circuit.
