TEMPERATURE COMPENSATION QUARTZ OSCILLATION CIRCUIT AND TEMPERATURE COMPENSATION METHOD THEREOF

摘要

Pair common primary input signal to the input terminal and the constant level signal of a predetermined level is input separately, output the inverted or non-inverted signal with respect to the first input signal with a drink, the output signal a predetermined maximum value and 6 and a differential amplifier (15A~15F) having a limiter for limiting a minimum value, and the constant level signal generating circuit which supplies a constant level of the signal to the differential amplifier 6, the energization current of the differential amplifier (15A~15F) and a current mirror circuit (14) for controlling, has the added resistance (16A, 16B) for adding the output current of the differential amplifier (15A~15F), in the sixth differential amplifier (15F), and a larger energizing current by increasing the resistance value, to obtain the output current of the high-precision components of the fifth order function also of the slope of the more sharply inclined with respect to the input signal. ; Inverting, non-inverting, the differential amplifier, functions, approximated
