1. A CMOS circuit, comprising:
- a silicon substrate having a CMOS-fabricated circuit therein; and
an image sensor device, formed on said silicon substrate using an MOS formation process, and configured in a way to produce a substantially instantaneous readout of an amount of incoming light incoming thereto without integrating said light and producing an electrical signal indicative thereof, said electrical signal forming an input signal for said CMOS fabricated circuit.

Abstract
CMOS optical receiver and optical transmitters are described. The optical receiver is formed from a CMOS CCD which is modified to immediately output all information indicative of incoming light, i.e., with no transfer gate. The optical transmitter is formed of a modulation window device. Both the optical transmitter and optical receiver are located on-chip with a microprocessor and form the I/O for the microprocessor. Since the modified I/O is serial, a serial to parallel converter, and parallel to serial converter are provided.
