Abstract
A voltage or current controlled current-feedback operational-amplifier based multivibrator provides oscillation based on two current feedback operational amplifiers, three resistors and one grounded capacitor. The multivibrator can achieve almost constant frequency of oscillation and its duty cycle can be adjusted by a control voltage or a control current. The multivibrator can be used for generating pulse-width modulated signals.
