Abstract

PURPOSE:To decrease the error in the steepness of slope due to the variance of top temperature of quartz oscillator, by selecting the reference voltage value according to the top temperature of quartz oscillator from a read-only-memory. CONSTITUTION:A programmable read-only-memory 442 selects resistors 455-457 integrated for top temperature adjustment according to the value of detected temperature, for the adjustment of the top temperature of quartz oscillator.
