Abstract
Apparatus for sensing a current across a known resistor comprising a switched capacitor network and an amplifier having an input coupled to an output of the switched capacitor network. The switched capacitor network is configured to sample first and second reference potentials indicating the current. The amplifier is configured to produce first and second amplified potentials at an output of the amplifier based on the first and second reference potentials.
