ABSTRACT:
An insubstantial amount of noise results at the output of a circuit when an output of a primary amplifier is disconnected from and reconnected to the circuit in which is operating. The primary amplifier is placed temporarily in a muting configuration. A secondary amplifier permanently in a muting configuration is connected in parallel with the primary amplifier. The output of the primary amplifier then is disconnected from a circuit node to which it is attached. The primary amplifier may then be taken out of its muting configuration. After, for example, configuring the primary amplifier as a comparator and calibrating its dc-offset voltage, the primary amplifier is placed back into a muting configuration. The secondary amplifier then is disconnected from the primary amplifier. The primary amplifier may subsequently be taken out of muting configuration to resume its normal function in the circuit.
