摘要

This paper presents a pulse-driven method for detecting Cardiac Troponin I using an electrical double-layer (EDL) capacitance sensing readout circuit and an on-chip pattern generator. The pattern generator is equipped with a slew rate-boosting driver circuit capable of handling EDL capacitance ranging up to 100 nF with a slew rate greater than 6.6 V /us while consuming only 13.5 μW. Additionally, the design achieves a dynamic range (DR) of 77.4 dB by implementing an oscillator-based readout circuit and a limit of detection (LoD) of 200 fg/mL in an undiluted PBS solution with a total power consumption of 120 μW.
