Abstract

PURPOSE:To reduce the power consumption, by providing Tr feeding bias to oscillation Tr at the operation of the oscillation circuit and reducing the operating current at oscillation, in the crystal oscillation circuit using complementary MOS transistor Tr. CONSTITUTION:In the crystal oscillator circuit using complementary MOS Tr, when the oscillation transistors T1 and T2 are in liner region, MOSTrT3 grounding the gate adding a bias to the linear region and MOSTrT4 connecting the gate to the power supply are connected between the source and power supply of TrT1, T2 respectively. Further, MOSTrT4 and T5 controlled in connection with the cell voltage detection circuit and biased at the linear region or interrupting state are provided, and the crystal oscillation circuit is constituted by connecting the crystal oscillator Q providing resonant capacitors C1 and C2, to TrT1, T2. Further, the power consumption of the oscillation circuit is reduced by connecting TrT3 to T5 according to the operating condition.
