CPC classification number: H03H19/004 ,  H03F3/45475 ,  H03K3/012 ,  H03K3/013 ,  H03F2203/45514 ,  H03F2203/45551

Abstract: An apparatus includes a differential current-to-voltage conversion circuit that includes an input sampling stage circuit, a differential integration and DC signal cancellation stage circuit, and an amplification and accumulator stage circuit. An input common mode voltage of the differential current-to-voltage conversion circuit is independent of an output common mode voltage of the differential current-to-voltage conversion circuit.
