ABSTRACT:
An operational amplifier having an adjustable input offset is provided that can improve dynamic performance by allowing processing of the input signal in continuous-time. The amplifier circuit comprises an input source and an operational amplifier configured with an adjustable input offset circuit. The adjustable input offset circuit enables cancellation of the offset error from any input sources prior to being translated or gained up by the operational amplifier, thus improving the dynamic range of the operational amplifier. The adjustable input offset circuit can be configured within a signal path of an auto-zero loop of the operational amplifier, or with a continuous-time implementation.
