Abstract
An analog front-end (AFE) for an impedance sensor uses digitally controlled impedances to modulate a differential input from an impedance-based sensor. The digitally controlled impedances may be coupled between the differential input and one or more reference voltages. In some embodiments use of the digitally controlled impedances may allow for omission of a preamplifier from the AFE, or a reduction in gain of the preamplifier, reducing noise associated with the preamplifier.
