摘要：

This paper presents a low-voltage operated instrumentation amplifier design for Enzyme-Extended-Gate Field-Effect Transistor (EEGFET) biosensor signal readout applications. The instrumentation amplifier built by three bulk-driven amplifiers fabricated in a 0.5mum double-poly double-metal CMOS technology and other off-chip resistors has been proved to have a potential application in urea sensor signal sensing. Key parameters of the bulk-driven amplifier and the instrumentation amplifier have been verified for the low-voltage signal readout consideration. The system for urea monitoring has been performed with 1.5V power supply. Experiment results show, that the developed instrumentation amplifier has at? acceptable sensing response of various urea concentrations in the range of 0.3125 to 240mg/dl.
