ABSTRACT:
A temperature balanced circuit is provided which is capable of, in case a CMOS.cndot.IC is utilized as a delay circuit, giving a constant delay time to an input signal to the delay circuit even if the frequency of the input signal is varied. A delay circuit 11 and a dummy circuit 11 having the same construction as that of the delay circuit are provided in a CMOS.cndot.IC. There are provided a counter counting first pulse signals CP1 supplied to the delay circuit during a fixed time interval and arithmetic unit finding a difference between a count value of this counter and a predetermined value, and the same number of second pulse signals as the difference value found by the arithmetic unit is supplied to the dummy circuit, thereby to define to a constant value both the number of the first pulses and the number of the second pulses supplied to the CMOS.cndot.IC within a unit time interval, which results in uniformity of an amount of heat generated in the CMOS.cndot.IC.
