Abstract :
A simple sinusoidal frequency-doubling circuit is proposed which incorporates operational amplifiers (op amps) with resistors as the only external components. The realization method makes use of the inherent translinear loop at the input stage of the op amp as a means to perform frequency doubling. The response of the circuit is discussed and experimentally demonstrated
