Title: Constant current circuit
Inventor: MORIGAMI TAKASHI
IPC: G05F3/18
Filed: 1988-12-21
Abstract: PURPOSE:To make a constant current circuit usable even for a comparator whose operation starting voltage is low and which depends greatly upon the balance of threshold voltage by using a diode and a Zener diode for a low voltage generating part. CONSTITUTION:A stable constant voltage circuit is constituted of the diode 36 and the Zener diode 37. Since the withstand voltage of the diode 36 is -2mV/ deg.C and the withstand voltage of the Zener diode 37 is 2 to 4mV/ deg.C, the constant voltage circuit is stable against temperature. Besides, a first resistor 35 is about 100KOMEGA, and acts to suppress a circuit current. The dark current of the constant current circuit is determined by the width and the length on a substrate of a transistor (TR) 33 whose gate signal is this constant voltage. Further, since the TRs 31, 32 constitute a current mirror circuit, an equal leak current flows in a second resistor 38 and the TR 34. Accordingly, a current stable against the voltage and the temperature is outputted to constant current output A.
