A multi-purpose sensor interface that provides dual-mode operation of fingerprint sensing and physiological signal detection is presented. The dual-mode sensing capability is achieved by utilizing inter-pixel shielding patterns as capacitive amplifier’s input electrodes. A prototype readout circuit including a fingerprint panel for feasibility verification was fabricated in a 0.18 mm CMOS process. A single-channel readout circuit was implemented and multiplexed to scan two-dimensional fingerprint pixels, where adaptive calibration capability against pixel-capacitance variations was also implemented. Feasibility of the proposed multi-purpose interface was experimentally verified keeping low-power consumption less than 1.9 mW under a 3.3 V supply. #Multi-sensor interface #fingerprint sensor #physiological sensor #readout integrated circuit #dual-mode operation
