Title: Oscillation circuit
Inventor: TOKAWA MAKIYO
IPC: H03B5/36
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To shorten the oscillation start time of a crystal oscillation circuit while the center potential of the output of the circuit is fixed and, at the same time, to reduce the power consumption of the circuit. SOLUTION: A crystal oscillation circuit is provided with a three-state inverter buffer 12 and an ON/OFF control circuit 11. At the time of starting the oscillation circuit to oscillate, the buffer 12 is turned on and the circuit is started with the total gain of the buffer 12 and a logic inverter 13. Since the power supply to a logic element is fixed, the center potential of the output to the succeeding stage does not vary, but is fixed. The oscillation of the oscillation circuit is continued by only using the gain of the logic inverter 13 by turning off the three-state inverter buffer 12 by means of the ON/OFF control circuit 11 after the time required for stabilizing the oscillation circuit has elapsed.  Since the oscillation circuit is made to make oscillating operations by only using the gain of the logic inverter 13 of a CMOS, the power consumption of the oscillation circuit can be reduced.
