Research Note Two novel voltage( current) controlled integrable oscillators
Muhammad Taher Abuelma ' Atti, RASHA HUSSAIN ALMASKATI · International Journal of Electronics · 1988
Two novel voltage( current) controlled oscillator circuits are presented. Each circuit uses a single operational amplifier, a single operational transconductance amplifier, and either a single resistor or a single capacitor. In both circuits the frequency of oscillation can be adjusted by changing the biasing voltage( current) of the operational transconductance amplifier. Experimental results are included
