Abstract

A simple floating current-controlled positive resistance (CCPR) circuit based upon two mixed translinear cells realized with bipolar junction transistors has been presented. The workability of the circuit and its application in realizing a variable-bandwidth bandpass filter and a new frequency shift keying generator have been confirmed by experiments and/or PSPICE simulations based upon CA3096 and ALA400 mixed transistor arrays. The proposed floating CCPR circuit appears suitable for implementation of a variety of electronically tunable analog signal processing/generation circuits in bipolar technology.
