Abstract

This paper presents a new configuration for a cascode current mirror with a pseudo resistive feedback utilizing bulk-driven transistors. The feedback part is realized with pseudo resistors to improve the regulation of the mirror and thus increases the output resistance. It also enables to reduce the headroom voltage of the current mirror. The detailed study of MOSFET is given along with an insight into the working of pseudo resistor. Simulation and analysis of the configuration was done using BSIM 4.4.0 model at 20nm with a supply voltage of 0.5V. An analytical model of the configuration is also presented. The layout work was done using n-well process in ELECTRIC and is included in the paper. Parasitic extraction of the Layout was also done and circuit was modified according to the simulation results of the spice file extracted from the layout.
