Abstract
An offset correction circuit which enables a designer to control the correction range irrespective of the amplification sought to be achieved to the image component of the input signal. The offset correction further enables the designer to perform offset correction to a low resolution. Both range and resolution can potentially be attained using only two stages thereby minimizing power consumption and also minimizing introduction of any undesirable components.
