As the voltages x1 and x2 drop, variable current sources 102a and 102b accelerate the drop of the voltages x1 and x2 by making currents flow to a grounding terminal from nodes x1 and x2. Consequently, comparable ranges of comparators 102a and 103b are expanded and stable photo-detection outputs can be taken out from the photodetecting circuit.  <P>COPYRIGHT: (C)2003,JPO
