Abstract
A CMOS switched capacitor instrumentation amplifier is presented. Offset is reduced by an auto-zero technique and effects due to charge injection are attenuated by a special amplifier configuration. The circuit which is realized in a 4-μm double poly process has an offset (τ) of 370 μV, an rms input referred integrated noise (0.5 -fc/2) of 79 μV, and consumes only 21 μW (fc = 8 kHz, VDD = 3 V).
