Classification: CPC G | IPC G

Claim 15:
16. A method, comprising:
producing an output of a process based on a reference value input, wherein the output is a temperature;
determining an output measurement value based on the output using a temperature sensor;
determining an error between the output measurement value and the reference value input;
generating a control signal based on the error; and
using the control signal to control the process with a quantizer, wherein the quantizer utilizes the control signal to generate a digital code, and wherein the digital code individually controls different coils of a heating array, wherein the heating array comprises a plurality of heating elements arranged in parallel, wherein each of the plurality of heating elements comprises a respective resistor coupled to a respective switch, wherein the respective switch is controlled by a respective bit of the digital code output, wherein the temperature sensor is surrounded by the plurality of heating elements.
