Abstract
Novel circuitry and methodology are provided for correcting the offset associated with a voltage-controlled current source. An offset correction circuit is coupled to the current source to prevent the output current produced by the current source from deviating from a desired level. The current source may include a transconductance amplifier or a chopper amplifier, and may be configured to produce a zero or non-zero value of the output current.
