Claim Text:
1. A system for regulating a temperature of a measurement array, comprising: a measurement array including a plurality of sensors, wherein the plurality of sensors are integrated onto an integrated circuit die; a thermal sensor integrated onto the integrated circuit die, wherein the thermal sensor senses a temperature associated with the plurality of sensors; and a heat pump coupled to the integrated circuit die and coupled to a heat sink, wherein the heat pump is controlled by a feedback control circuit including the thermal sensor; wherein the feedback control circuit includes an amplifier coupled to the thermal sensor and further includes a thermoelectric controller; and wherein thermal behaviors of the system are represented by a thermal model including a plurality of thermal parameters, wherein the thermal parameters comprise thermal resistances and thermal capacitances measured with respect to a plurality of components of the system, including the heat pump, the heat sink, and the integrated circuit die, and wherein the system forms an asymptotically Lyapunov stable linear control loop based at least in part on satisfying a plurality of relationships between two thermal parameters associated with the thermal model, the plurality of relationships comprising: a thermal resistance between the integrated circuit die and ambient air surrounding the integrated circuit die is substantially larger than a thermal resistance between the heat sink and ambient air surrounding the heat sink.
