Integrator input error correction circuit and circuit method

A circuit comprising:

• an integrator configured to receive an input current, wherein the integrator includes:
• a first amplifier and a second amplifier, wherein first amplifier is configured to receive the input current at a first input of the first amplifier, and an output of the first amplifier is configured to drive a first input of the second amplifier;
• a pull-up current source selectively coupled to the first input of the second amplifier;
• and
• a pull-down current source selectively coupled to the first input of the second amplifier;
• wherein if the absolute value of the input current is larger than a predefined threshold current:
• the pull-up current source is configured to drive current into the first input of the second amplifier for a first polarity of the input current, and
• the pull-down current source is configured to sink current from the first input of the second amplifier for a second polarity of the input current.
