摘要： An optical-to-electrical converter includes an input port configured to receive an optical signal. The converter further includes a splitter configured to split the received I optical signal into a plurality of optical signals. An optical stage has a plurality of parallel stages, and each parallel stage receives a corresponding one of the plurality of identical signals and outputs a corresponding one of a plurality of sampled optical signals within a corresponding sampling window. A plurality of delay circuits receive a clock signal having a plurality of clock pulses separated by a clock period. The delay circuits respectively output a plurality of control pulses at a plurality of delayed timings with respect to each clock pulse of the clock signal. An electrical stage receives the plurality of sampled optical signals and processes the optical signals at a sampling rate corresponding to the clock period of the clock signal.

摘要： An imaging apparatus includes a pixel, a current source, and a signal processing circuit. The pixel outputs signal charge, obtained by imaging, as a pixel signal. The current source is connected to a transmission path for the pixel signal and has a variable current. The signal processing circuit performs signal processing on a signal depending on an output signal to the transmission path and performs control so that a current of the current source is changed in accordance with the result of signal processing.
