Claim 15:
16. An on-chip power-controlled heater, comprising:
a heater resistance;
a heater digital-to-analog converter (DAC) configured to provide a current to flow through the heater resistance based on a digital current code provided to the heater DAC;
an analog-to-digital converter (ADC) configured to monitor a voltage across the heater resistance and convert the voltage to a digital voltage code;
a digital multiplier configured to multiply the digital voltage code with the digital current code to generate a heater power code; and
a bidirectional counter configured to update the digital current code to regulate power dissipated by the heater resistance based on comparison of a reference power code and the heater power code.
