Abstract:
A precision digital to analog conversion circuit and method are provided. A regulated direct current (DC) voltage having a DC voltage magnitude is supplied to a device, such as a processor. The processor generates a pulse width modulation (PWM) output signal based, at least in part, on the regulated DC voltage. An analog output signal is generated from the PWM output signal. The regulated DC voltage is compared to a precision reference DC voltage, the DC voltage magnitude is selectively adjusted based on the comparison.
