Title: Photodetector
Inventor: SUZUKI TAKAYUKI
IPC: H04B10/43
Filed: 2004-07-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a photodetector applicable to such communication as requiring a wide dynamic range at high speed.  <P>SOLUTION: When photocurrent output from a photodiode 14 for detecting optical power lowers below a specified level, output from a comparator COMP1 is switched abruptly but since a low-pass filter SC removes harmonic components, its output, i.e. the voltage at a gain control terminal VG, lowers gradually. Since the amount of current flowing between the source-drain of an N type MOS transistor GCT for gain regulation being applied with that voltage decreases gradually, the amount of current flowing through a resistor R1 decreases and the resistance Rx of the combined resistor in a gain regulation amplifier AMP increases thus increasing the gain thereof up to a specified level. Although the time required for the output voltage to increase and saturate is within 3 μs, adverse effect on a PHY chip being connected with the post-stage can be suppressed by changing the gain of output voltage slowly.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
