Abstract
Measurement circuitry comprising: a first half bridge, comprising: a first impedance coupled between an input voltage node for receiving an input voltage and a first node; and a second impedance coupled between the first node and a reference voltage node, the first impedance or the second impedance comprising a first voltage-controlled oscillator (VCO) having a first input coupled to the first node and a first output for outputting a first oscillating signal having a first frequency proportional to a current flowing in the half bridge.
