Title: Frequency doubling circuit for symmetrical rectangular voltage - has two integrators delivering doubled frequency through logic circuit at their outputs
Inventor: ESCHKE BERND ING GRAD
IPC: G06F7/68
Filed: 1976-05-15
Abstract: The circuit comprises two integrating differential amplifiers (integrators). Their first inputs are connected to a reference voltage, and voltages of the same frequency but with phases differing by 180 deg. are applied to their second inputs. This voltage is higher or lower than the reference voltage. The ratio of voltage difference at the inputs of integrators to the respective time constant when the higher voltage is applied, is half of that when the lower voltage is applied. A device is allocated to the integrator which prevents the integrator output voltage from exceeding the reference voltage. A recognition circuit is allocated to each integrator, which responds when the integrator voltage reaches the reference voltage, and delivers a signal so long as this state lasts. These signals are so logically linked, that when these signals are present, a certain voltage level appears at the circuit output.
