摘要：An infrared remote-control receiver employs at its front end a gyrator-configured transistor operating as a current-to-voltage converter, but derives its datainformation from a negative-going gyrator output pulse in preference to the moreconventionally used positive-going pulse. This negative-going pulse may be wider thanthe positive-going pulse and reduces the bandwidth demand on subsequent processingcircuitry. This enables low-bandwidth, low-current hardware to be used which makes thereceiver ideal for use in battery-operated systems. Also, the negative- going pulse iseasier to detect, as it directly follows a disturbance known to be in the oppositedirection. The result is an increased receiver sensitivity.
