Abstract

By using two resistors and a single capacitor with second-generation differential current conveyor as an active element, a new square wave generator is proposed and implemented. The frequency of operation of the introduced model is varied with respect to the variation of remaining passive components. Maximum reduction in noise effects caused by parasitics generated during integrated circuit fabrication is achieved with the scheme of grounded capacitor. The mathematical model of the selected circuit is verified in both simulation and experimental mode and found having matched in all three aspects. The elevated advantages and merits of the given topology are compared and tabulated contrary to the existing standard models. Using Cadence virtuoso with gpdk 180 nm libraries, the circuit is verified with a supply rail voltage of ±2.5 V. Later, prototype is also tested with commercially available current feedback operational amplifiers of AD844AN.
