Charge sensitive pre-amplifier architectures have been studied for decades for various applications, most of which adopt a gain stage with capacitor feedback to integrate the signal and a reset path to provide DC bias. For the biological temperature readout front-end, we propose a novel structure without the gain stage, which implies a strong potential for fully integrated high frequency applications. The proposed design provides 0.94 mV/pC with high conversion linearity while consuming only 1.4 micro watts of power with buffer under a 1.2-V supply rail. The prototype occupying a chip area of 0.038 square millimeter is fabricated in 130 nm standard CMOS process.
