Classification: CPC G  H | IPC G  H

Claim 8:
9. The on-chip heater of claim 8, wherein the monitored electrical characteristic of the heater circuit is a monitored voltage drop across the heater resistance and the heater power controller includes:
an analog-to-digital converter (ADC) configured to convert the monitored voltage drop across the heater resistance 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 a comparison of a reference power code and the heater power code.
