Abstract
A chopper stabilized current amplifier circuit is disclosed. The current amplifier circuit includes a main operational transconductance amplifier, a nulling transconductance amplifier, two capacitors, four switches, and a timing control circuit. The timing control circuit uses analog inverters to decrease the slew rate of the switching of the switches to decrease the noise in the system.
