Abstract

A proximity sensor (200) comprises a reference inductor (L21), a first set of sensor inductors (L22, L23, L24), a first set of comparators (U22, U23, U24), each comparator of the first set of comparators corresponding to one of the sensor inductors of the first set of sensor inductors, and an alternative current voltage source (V21) to output a sinusoidal voltage to the reference inductor and each of the sensor inductors. Each comparator of the first set of comparators (U22, U23, U24) receives a voltage across the reference inductor (L21) as a reference voltage and each comparator of the first set of comparators (U22, U23, U24) receives a voltage across a corresponding sensor inductor (L22, L23, L24) as an input voltage.
