Abstract :
A simple method to synthesise oscillator circuits employing only one unity-gain amplifier is presented. It is shown that any oscillator formed by one inverting infinite-gain ideal amplifier looped back by a perfect band-reject filter will automatically give rise, through a simple transformation, to an oscillator circuit employing only one unity-gain amplifier. It is further shown that the passive network must be at least a third-order band-reject filter.
