Abstract
A system-on-chip contactless physiological sensor () is provided which comprises a capacitive-sensor electrode () having a first capacitance (C) and an amplifier device () connected to the capacitive-sensor electrode (), the capacitive-sensor electrode () and amplifier device () at least in part forming an amplifier circuit for the physiological sensor (). An artefact-reducing capacitor () is then connected in series between the capacitive-sensor electrode () and an input of the amplifier device (), the artefact-reducing capacitor () having a second capacitance (C) which is less than the first capacitance (C). In this sensor (), there is no impedance boosting input between the capacitive-sensor electrode () and the input of the amplifier device ().
