Item type:Publication, Simple CCO using cciis and S-R latch and its application(2010-06-01); ; ; Sasaki, HlrofumiThis 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. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Dual slope analog-to-digital converter using simple CCII-based integrator(2010-10-01); ; Sasaki, HorofumiThis article presents a dual slope analog-to-digital converter (ADC) using second generation current conveyor (CCII)-based integrator. In comparison with the previously reported dual slope ADCs with grounded capacitor, the proposed configuration offers simpler structure and fewer components while utilizing the positive reference voltage. Experimental results are given to confirm the operation of the proposed ADC. ICIC International © 2010 ISSN.
