Beschreibung
Zusammenfassung:	Disclosed are a sensor circuit system (10), a related chip and an electronic device. The sensor circuit system comprises a charge pump circuit (102), configured to provide a charge pump supply voltage (V DD) having an adjustable level; an analog circuit (104), coupled to the charge pump circuit and configured to receive the charge pump supply voltage as a voltage source of the analog circuit, and operate at the charge pump supply voltage to output an analog signal (S ANA); an analog-to-digital converter (106) coupled to the analog circuit and configured to convert the analog signal into a digital signal (S DIG); and a digital signal processing module (108) configured to obtain a signal-to-noise ratio of the digital signal and generate a control signal according to the signal-to-noise ratio so as to adjust the level of the charge pump supply voltage provided by the charge pump circuit.
