Reference Circuit

In this paper, an all CMOS current reference circuit which generates a reference current independent of PVT (Process, supply Voltage, and Temperature) variations is presented. The circuit consists of a self-biased current source (SBCS) and two nested connected transistors which supply a voltage with positive temperature coefficient and the resulting reference circuit has low temperature coefficient. It is based on CSMC 0.5um mixed-signal process with the supply voltage of 5V. The precision of reference current is about ±3.05% when considering the process, supply voltage and temperature variation at the same time.
