摘要
A fully integrated CMOS bio-chip is designed in a SMIC 0.18μm CMOS mixed signal process and successfully integrated with a novel bio-nano-system.The proposed circuit integrates an array of 4×4(16 pixels)of 19μm×19μm electrodes,a counter electrode,a current mode preamplifier circuit(CMPA),a digital decoding circuit,and control logics on a single chip.It provides a-1.6～1.6V range of assembly voltage,8bit potential resolution,and a current gain of 39.8dB with supply voltage of 1.8V.The offset and noise are sma...
