Title:
OSCILLATION CIRCUIT AND OPERATING CURRENT CONTROL METHOD OF SAME
Document Type and Number:
WIPO Patent Application WO/2011/158576
Kind Code:
A1
Abstract:
Disclosed is an oscillation circuit comprising a capacitor, a charge and discharge unit for switching between charging and discharging of the capacitor according to a control signal, a comparator for comparing the voltage of the capacitor with a reference voltage to output a comparison result signal, a flip-flop which is set or reset with the comparison result signal and which supplies the output signal as a control signal to the charge and discharge unit and outputs the output signal as an oscillation signal, and a current control unit for controlling the operating current of the comparator according to the voltage of the capacitor.
