Design and Analysis of Linear Voltage to current converters using CMOS Technology

Voltage to current converters or TRANSCONDUCTANCE amplifiers, find its applications in both traditional analog ICs e.g. amplifier and filters as well as current analog VLSI e.g. Field programmable analog arrays and various other neural networks. A complete review of different linear V-I converter has been done in this paper. Since the basic V-I convertor circuit uses common source differential pair which shows the nonlinearity effect due to the differential input voltage signal. The different circuits like Linear composite MOSFET TRANSCONDUCTOR, linear V-I convertor including feedback network which are designed to overcome the problem of non linearity has been studied. The basic V-I Converter using source coupled differential pair was synthesized and simulated using Mentorgraphics, Pyxis Schematic and ELDO respectively using 0.25 nm technology. 1.
