Median-based offset cancellation circuit technique

A simple technique to compensate for DC offsets in many analog circuits is presented. An offset-free, infinite DC gain integrator is established in a feedback loop about the uncompensated circuit, resulting in a high-pass system output response. The ideal integrator is realized via the use of a counter resulting in the cancellation of the signal's median rather than the usual case of the signal's mean.<<ETX>>
