Assignee: WINBOND ELECTRONICS CORP.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A clock-generating circuit, comprising:
a voltage-reference circuit, converting an external voltage into a reference voltage;
a tracking-voltage-generating circuit, converting the external voltage into a temporary reference voltage;
a voltage regulator, receiving the reference voltage and the temporary reference voltage, and converting the reference voltage or the temporary reference voltage to an oscillation power-supply voltage;
an oscillation generator, generating a first clock signal according to the oscillation power-supply voltage; and
a level shifter, converting a voltage amplitude of the first clock signal to generate a second clock signal output by the clock-generating circuit,
wherein the voltage regulator comprises a switch circuit for controlling whether to pull up the oscillation power-supply voltage, which is at an output terminal of the voltage regulator, to the external voltage according to an enable signal.
