An analytical approach to the design of compact CMOS chopper amplifiers for integrated thermoelectric sensors is presented. The impact of the high resistance and low signal bandwidth of thermopile sources on the design is illustrated. The proposed approach, regarding the precision vs noise tradeoff, is applied to the design of a practical prototype, using a commercial process. Accurate electrical simulations are provided to confirm the effectiveness of the proposed design methodology
