Abstract :
New simple sinusoidal oscillator circuits are proposed. Each circuit uses an internally compensated operational amplifier, a resistor and a capacitor. The feasibility of obtaining digitally programmable sinusoidal oscillation is studied and a new digitally programmable capacitorless resistorless sinusoidal oscillator is developed
