Patent ID: 11949336
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A voltage regulator, comprising:
a first energy storage element and a second energy storage element configured to contribute to an output signal;
a reference channel configured to:
receive a reference signal pathway regulation signal and a first switching clocking signal; and
provide a first charging signal to the first energy storage element;
a regulator channel configured to provide a second charging signal to the second energy storage element;
a global error circuit configured to compare the output signal with a reference input signal to provide a global error signal;
a combination circuit coupled to the global error circuit and the reference channel, wherein the combination circuit is configured to combine the global error signal and a reference signal pathway error signal to provide the reference signal pathway regulation signal; and
a local error circuit configured to compare the first charging signal prior to being received by the first energy storage element with the second charging signal prior to being received by the second energy storage element to provide a local error signal, wherein the local error signal contributes to a correction of the second charging signal.
