Abstract
A technique for chopper-stabilizing commercial linearized operational transconductance amplifiers (OTAs) to remove output offset current errors is described. Design equations which illustrate performance tradeoffs as a function of component values are given. The results are verified experimentally using a common bipolar OTA
