Abstract
We present a CMOS circuit used for controlling the temperature of a CMOS compatible micro-heating element, known as a thermal pixel. The circuit uses nonlinear compensation to maintain constant power over large variation in the resistance. An external analog voltage controls the power delivered to the thermal pixel. This circuit was designed and fabricated through the MOSIS service foundry. Measurements are presented that verify the design and performance of the circuit
