Abstract
Current sensing circuits for motor control applications are discussed. In some embodiments, a circuit may include a shunt resistor network coupled to an inverter having a plurality of phase legs, where each of the plurality of phase legs is configured to drive a respective phase of an electrical motor, and an Operational Amplifier (Op Amp) coupled across the shunt resistor network, where the Op Amp enables a processor to reconstruct electrical currents in each of the plurality of phase legs.
