Abstract

Abstract : This research paper brings an instrumentation amplifier (IA) that exhibits all possible mode specifically voltage, current, transadmittance, and transimpedance mode using a single differential voltage current conveyor (DVCC) and few active resistors using transistors. The proposed design offers high range of 3 dB frequency for both differential gain ( Ad ) and common mode rejection ratio (CMRR). The introduced topology of different IA are analyzed and simulated with PSPICE using 0.18 µm CMOS technology parameter for the realization of DVCC. Also, the experimental verification using commercially available Current Feedback Operational Amplifier (CFOA) named as IC AD844 is used to check the practical feasibility of proposed design. Apart from the ideal analysis of IA, nonidealities of the proposed work, temperature-dependent variation that affects the nature of IA, Monte Carlo simulations are well depicted in this report.
