Abstract:

An on-chip thermoelectric cooler (TEC) controller with improved current driving capability, is designed and implemented in a standard 65 nm CMOS technology, with VDD of 1 V. The fully monolithic controller incorporates the error amplifier, the control and compensation mechanism, the driver circuitry, the filter, and the current enhancement circuit. The filter is devised using a second-order circuit with transconductance-capacitance (GmC based active inductor. The proposed controller comprises the high-swing current driver at the output stage to satisfy the increased and stable current requirements for larger cooling demands. The extensive simulation results show an output current limit of 2 A, and an efficiency (\eta) level of 85% at a load of 0.5 \Omega. In the case of output current and efficiency, respectively, the statistical mismatch analysis shows 15 \mu \mathrm{A} and 0.7% of mean deviation over 6 \sigma in the temperature range of -20^{\circ}\mathrm{C} to + 100^{\circ}\mathrm{C}.
