Abstract :
A new transconductance-amplifier-capacitor sinusoidal oscillator configuration is introduced which requires only three OTAs (in contrast to previously known circuits which employ four to five OTAs) to facilitate generation of linearly tunable (through an external current or voltage) variable frequency oscillations.
