Novel CMOS differential voltage current conveyor and its applications

Abstract

Novel CMOS realisations of a differential voltage current conveyor (DVCC) are described. These circuits are powerful building blocks, especially for applications demanding differential or floating inputs like impedance converter circuits and current mode instrumentation amplifiers. Applications suitable for VLSI are then considered by using the DVCC to realise a MOS transconductor and a continuous-time current mode MOSFET-C filter. PSpice simulations indicate the excellent performance of the proposed DVCC and of its circuit applications.
