Abstract :
A micropower chopper-stabilized opamp uses an SC notch filter with synchronous integration inside the CT signal path to eliminate chopping noise. Characteristics include rail-to-rail I/O, 15muA supply current at 1.8 to 5.5V, 2muV offset, 55nV/radicHz noise, 350kHz GBW, and a chopping frequency of 125kHz. The die area is 0.7mm2 using 0.6mum CMOS
