Abstract

PURPOSE: To ensure a high sensitivity in a simple way regardless of the dispersion of the characteristics of the detection diode by using the bias current obtained by piling the AC current onto the AC or DC current as the bias current source.
CONSTITUTION: The detected signals are supplied from input terminal 8 and then applied to detection diode D1 via filter 10. While the DC current obtained by piling the AC current onto the AC or DC current is supplied to D1 in the form of the bias current from bias terminal 5 and via filter 11. Then the detection output voltage occurring across output load resistance 7 is drawn out from output terminal 4 via filter 9.
