ABSTRACT

The purpose of this paper is to introduce a new CFTA based resistor less electronically tunable multi- phase oscillator. The proposed circuit provides independent control of frequency of oscillation without disturbing the condition of oscillation. Design/methodology/approach – The current/voltage-mode oscillator has been designed using a second order low-pass filter and a non-inverting lossless integrator with the unity feedback system using CFTA oscillator.
