Popis: Two new active-only sinusoidal oscillator circuits are proposed. The first circuit uses one current feedback operational amplifier (CFOA) and four operational transconductance amplifiers (OTAs). The second circuit uses only four OTAs. Without using any external passive elements, voltage (or current) control of the frequency and condition of oscillation, of the two circuits, can be achieved by adjusting the bias currents of the OTAs. The proposed circuits enjoy low sensitivities.
