Patent ID: 11913980
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A device comprising a power detection circuit, wherein the power detection circuit comprises:
a comparator circuit operative to generate an output signal in response to an input signal, wherein the comparator circuit being operative to generate the output signal comprises the comparator circuit being operative to:
generate the output signal comprising a first logic value in response to the input signal attaining a first threshold value, and
generate the output signal comprising a second logic value when the input signal subsequently attains a second threshold value, the second logic value being different than the first logic value;

a current limiting circuit connected to the comparator circuit and operative to limit a leakage current of the comparator circuit; and
a feedback circuit connected to the comparator circuit and operative to control the first predetermined threshold and the second predetermined threshold, wherein the current limiting circuit is connected in parallel to the feedback circuit.
