Current Summing Mode CMOS Current Reference
Min Cai · Semiconductor Technology · 2005
Based on a method of temperature compensation,a novel super performance CMOS current reference circuit is presented. It is realized using the 0.35μm N-well CMOS process. The simulation results for this circuit using Cadence Spectre tools show that the temperature coefficient is less than 40×10-6/℃ in the range -40-85℃. The power consumption is about 1.2mW at 3.3V power supply. So it' s a low temperature coefficient and low power consumption current reference.
