Abstract
PURPOSE:To facilitate integration, by using the output of a reference oscillator as a time reference and measuring the output of a temperature detection oscillator to dispense with analogue processing. CONSTITUTION:The output phi402 of a reference oscillator 15 of relatively small temperature coefficient is frequency-divided by frequency dividers 16, 17. An output signal phi404 is applied to a gate circuit 18. Another output signal phi406 is transmitted as a set input to a counting circuit 23. Still another output signal phi406 is transmitted as a latch input to a latch circuit 20. The output phi401 of a temperature detection oscillator 14 of relatively large temperature coefficient is transmitted to a gate circuit 18. The output phi405 of the gate circuit is transmitted to the counting circuit 23. The outut phi407 of the counting circuit is changed into a signal phi408 through the latch circuit 20. The signal phi408 is applied to a driving circuit 21. The output phi409 of the driving circuit is applied to a display element 22. Since analogue processing by an operational amplifier or the like is not needed altogether, integration can be very easily effected.
