FGMOS based wide range low voltage current mirror and its applications

Low voltage current mirror (LVCM) based on floating gate MOSFET (FGMOS) has been presented in this paper. The LVCM has output current range of 100 nA to 500 /spl mu/A, high output resistance (1.35 M/spl Omega/ at 500 /spl mu/A), high bandwidth (500 MHz) and low input compliance voltage (0.4 V at 20 /spl mu/A input current and 0.6 V at 300 /spl mu/A input current). The LVCM design has been verified using P-Spice for 0.5 /spl mu/m technology and the error in current transfer is observed to be less than /spl plusmn/0.1%. Simulations have also been carried out for p-type LVCM and bipolar LVCM.
