CMOS Differential Voltage Current Conveyor using 0.25μm Technology

Abstract

CMOS realization of a differential voltage current conveyor based on transconductor is described in this paper. This is suitable for application demanding difference or floating inputs like impedance converter circuits. Application suitable for VLSI is developed by the DVCC like instrumentation amplifier, multiple input single outputs (SIMO) filter. Simulations of differential voltage current conveyor are given using 0.25μm CMOS technology from TMSC CMOS technology parameters. The circuit operates on supply voltage of ± 1.5V. Schematic is also analyzed. Layout is drawn in IC Station of Mentor Graphics. Post layout simulation is done and compared with pre layout simulation results using TSMC 0.25μm CMOS process model.
