A microvoltmeter circuit is designed to measure extremely low DC voltages, typically in the millivolt ( ) or microvolt ( μVmu cap V
) range. These circuits require high-precision components, such as chopper-stabilized operational amplifiers, to minimize DC drift and internal noise that can easily overwhelm such small signals.
