(US5811867-A)      The receiver (10) detects and processes light from a communication apparatus which transmits data in the form of light. The receiver has a light-receiving semiconductor chip (11) with buffer circuit, formed based on the first manufacturing conditions to output shaped voltage waveform.    A signal-processing semiconductor chip (12), formed based on the second manufacturing conditions, receives the output voltage of the light-receiving semiconductor chip to generate a digital data. The light-receiving and signal-processing semiconductor chips are provided in one package (13).    USE/ADVANTAGE -   For e.g. TV remote control. Reduces manufacturing cost due to reduced light receiver size. Ensures inexpensive utilisation in remote control system with few radio interference. Ensures easy designing on electric apparatus using light receiver due to reduced external constraint.
