Abstract

PURPOSE:To increase the stability of temperature characteristics, by connecting a series circuit consisting of a diode and a resistor to the collector of a transistor (TR) to which a control input is applied, and giving a collector potential to a current Miller circuit supplying injection current to an I<2>L inverter. CONSTITUTION:Taking a current flowing to a resitor R7 as I7, currents I2, I3 flowing to resistors R2, R3 are expressed as I2=I7R6/R2 and I3=I7.R6/R3, and the cur rents I2, I3 are determined with the resistance ratio in and IC. A diode 5 acts like the termperature correction of TRs Q1-Q7. Since the emitter current of a TRQ12 can be changed with a resistor R7, the oscillation frequency of a ring oscillator 4 consisting of the I<2>L inverter can be changed.
