| Abstract | Various bioFET sensor readout circuits and an operation method thereof are provided. The readout circuit comprises: a plurality of logic gates coupled with a cascade scheme, each of which includes at least one bioFET sensor; a delay extractor designed to generate a pulse width signal based on a time difference between an output signal and a reference signal from the plurality of logic gates; and a counting module designed to receive the pulse width signal, and to output a digital count corresponding to the width of the pulse width signal.
다양한 bioFET 센서 판독 회로 및 그 동작 방법이 설명된다. 판독 회로는 캐스케이드식으로 커플링되는 복수의 논리 게이트, 지연 추출기, 및 카운팅 모듈을 포함한다. 복수의 논리 게이트의 각각의 논리 게이트는 적어도 하나의 bioFET 센서를 포함한다. 지연 추출기는, 복수의 논리 게이트로부터의 출력 신호와 기준 신호 사이의 시간차에 기초하여 펄스 폭 신호를 생성하도록 설계된다. 카운팅 모듈은 펄스 폭 신호를 수신하고 펄스 폭 신호의 폭에 대응하는 디지털 카운트를 출력하도록 설계된다. |
