Abstract
A chopper-stabilized amplifier (A) includes an amplifier (), an input chopper (A) having a first input () receiving an input signal (V), an output () coupled to a first input of the amplifier, and a feedback resistor () coupled to an output () of the amplifier to couple a feedback signal (V) to a second input of the amplifier (). The input chopper operates in response to a chopping clock (CHOP_CLK). If the amplifier () is unacceptably close to a saturation condition, the chopping clock (CHOP_CLK) is disabled to reduce input leakage current (I) of the chopper-stabilized amplifier.
