Abstract
This article presents a, simple circuit technique based on commerciallyavailable devices to realize current controlled, oscillator (CCO) with twolow-impedance input terminals. By suitably setting two input signals, the linearfrequency-current relation of the proposed CCO can be either positive ornegative slope in the same circuit configuration. The oscillating outputfrequency linearly proportional to the difference between two input currents canbe obtained. The realization method is employed in second-generation currentconveyors (CCIIs) and, Set-Reset (S-R) latch. Experimental results verifyingperformances of the proposed, CCO are closely agreed, with expected, values. Toshow the usefulness of the proposed, oscillator, an application example incurrent-mode variable- frequency control for buck converter is also included.ICIC International © 2010.
