Abstract
A receiver circuit for a sensor includes a photosensitive input circuit and a logarithmic-signal circuit including a PN junction coupled to a pulse voltage node. The pulse voltage node may be coupled to the P-type terminal of the PN junction and an output of the photosensitive input circuit. In some examples, the receiver circuit also may include a linear-signal circuit and/or a square-root-signal circuit.
