This paper presents an ultra-low-power low-noise Capacitively-coupled Chopper Instrumentation Amplifier (CCIA). A current-reuse telescopic topology in the first stage along with a recycling folded-cascode topology in the second stage consumes net bias current of 26 mu A with enhanced efficiency and achieves an input-referred noise power-spectral-density of 12.77nV/root Hz. The proposed CCIA is chopped at 50kHz to bring the input-referred offset around 6 mu V and flicker-noise corner around 400mHz. Implemented in chartered 0.18 mu m CMOS process and designed for Thermoresistive Micro Calorimetric Flow (TMCF) sensors, the reported work achieves an excellent Noise Efficiency Factor (NEF) of 2.5 which is the lowest ever reported NEF for such applications. |
