Abstract
An interface circuit for a sensor including: a first injection-locked oscillator having: a first input coupled to a sensor, a free-running oscillation frequency of the first injection-locked oscillator being controlled by a signal from the sensor; and a second input coupled to receive a synchronization signal at a reference frequency, the first injection-locked oscillator being adapted to generate an output signal at said reference frequency, the output signal being phase shifted with respect to the synchronization signal as a function of the signal from the sensor.
