    Abstract: A current sensor includes a die and a shunt resistor having a first temperature coefficient and having a first node and a second node fabricated onto the die, wherein the shunt resistor is for passing the current that is to be sensed. A first compensation resistor is fabricated onto the die and is coupled to the first node of the shunt resistor, wherein the first compensation resistor is proximate the shunt resistor and has a temperature coefficient that is similar to the temperature coefficient of the shunt resistor. A second compensation resistor is fabricated onto the die and is coupled to the second node of the shunt resistor, wherein the second compensation resistor is proximate the shunt resistor and has a temperature coefficient that is the close to the temperature coefficient of the shunt resistor.

    Abstract: A circuit includes an amplifier output stage that includes a high switch and a low switch that generates a pulse width modulated (PWM) output signal to provide a load current to a load in response to a PWM input signal. The circuit includes a high gate drive that drives the high switch with a PWM high drive signal derived from the PWM input signal. This includes a low gate drive that drives the low switch with a PWM low drive signal derived from the PWM input signal. The circuit includes an edge corrector that adjusts at least one of a leading edge and a trailing edge of the PWM input signal to compensate for response time differences with respect to a direction of the load current to the load.
