Abstract
A signal voltage from a signal processing path is coupled via an interfacing terminal to an input port of a filter, the output port of which is connected to the base input of a current source transistor to supply thereto a signal voltage which exhibits the filter transfer function. The collector output of the current source transistor is also coupled to the interfacing terminal and conducts a current exhibiting the filter transfer function to the signal path via the interfacing terminal. The base input of the current source transistor is driven with filter output sigals via a low output impedance voltage source (e.g., an emitter follower stage). The impedance presented to the base of the transistor is primarily determined by the low output impedance of the voltage source.
