The output part of a power circuit with a temperature characteristic 31 is connected to the power voltage of a CMOS inverter-type oscillator circuit 4 including a crystal vibrator. The power circuit with a temperature characteristic 31 includes an amplifier 2 , a diode 20 and a resistor 11 . The output end V 2 of the amplifier 2 is connected to the anode of the diode 20 . The cathode of the diode 20 is connected to the negative input end V 3 of the amplifier 2 and one end of the resistor 11 , and the other end of the resistor 11 is grounded. To the positive input end V 1 of the amplifier 2 is connected a voltage source 1 with small VCC variations.
