Abstract

The paper reports on the design and experimental results of an application specific integrated Circuit (ASIC) based impedance sensor system. The system consists of an integrated analog front-end circuit for sensing impedance changes of multiple transducers, an LED driver, a low dropout regulator, an analog to digital converter, a 32-bit microprocessor, and an I2C communication module. The system was fabricated in a commercial 180 nm CMOS technology with an area of 2.265 mm2 and simulated power consumption of the Analog Front-End, ADC, LED driver, and power management modules of 20.05 mW, with the microprocessor consuming an additional 81 mW of power.
