Abstract
PURPOSE: To apply this circuit to a monolithic IC, by offsetting the dispersion of voltage and the dispersion of resistance values by utilizing a Zener diode with breakdown voltage proportional to the dispersion of resistance, in a constant-current circuit.
CONSTITUTION: A series circuit of a 2nd Zenor diode Dz2 and a resistance R11 is mounted to the output of a constant-voltage circuit arranged by a series circuit of a 1st Zenor diode DZ1 and a load resistance R10 -that is, in parallel with the Zenor diode DZ1. To change current flowing through the resistance R11 into constant-current, the concn. of impurities at the high resistivity side ranges over an unsaturated range of the characteristic of the concn. of impurities to Zenor breakdown voltage in the 1st Zenor diode DZ1, and it ranges over a saturated range in the DZ2 while a semiconductor range simultaneously shaped with a semiconductor range at the high resistivity side of the Dz1 is used as the resistance R11.
