ZC-CDTA based integrator circuit using single passive component

Abstract

An integrator with a single passive component based on Z-copy current differencing transconductance amplifier (ZC-CDTA) is introduced in this paper. The major advantage professed in the circuit is that it uses a single ZC-CDTA and one capacitor. The proposed integrator circuit was operated under ±0.9 V supply voltage with bias current of 100 µA by means of Cadence tool with model constraints of gpdk 180 nm in CMOS technology. Monte Carlo results for transient response and noise analysis results are also depicted in the results section of this paper. The total power dissipation of this circuit is 1.2546 mW. The proposed integrator circuit is useful for instrumentation and measurement applications.
