Title: Optical reception circuit
Inventor: SUEHIRO YOSHIKAZU
IPC: H04B10/2507
Filed: 1986-07-11
Abstract: PURPOSE:To reduce the fluctuation in pulse width and to decrease signal errors by connecting a + input terminal and - input terminal of a comparator via a resistor in an optical digital link and connecting the + and - input terminals to each bias potential. CONSTITUTION:The + input terminal and - input terminal of the comparator 21 are connected via a resistor, the said + input terminal 23 and the - input terminal 22 are connected to a bias potential respectively and a photodetector 31 is connected to the + input terminal or the - input terminal. An optical current 34 flowing through a photodetector (pin-PD)31 is denoted by (i) and resistances of resistors 25-27 are by R (the same value for three resistors) when V+ is a potential of the + input terminal 22 of the comparator 21 and V- is a potential of the - input terminal 23 of the comparator 21, then the voltage V+ rises by 2Ri/3 in the presence of the optical signal more than that in the absence of optical current and the voltage V- is increased by Ri/3. Thus, the output falls from the center point of the voltage V+41 with a small delay and the pulse width fluctuation characteristic is reduced.
