High-Purity and Wide-Range Signal Generator for Bioimpedance Spectroscopy.
IEEE Transactions on Circuits and Systems II: Express Briefs（2018）
摘要
This brief presents an integrated high-purity current signal generator (SG), part of a bioimpedance spectroscopy system that performs measurements in the frequency range from 1 kHz to 2 MHz, and it is able to measure bioimpedance values from 100 Ω to 1 MQ. The SG is implemented in a 0.18-μm CMOS process, it is powered by a single 1.8 V voltage source, and occupies a total area of 1.62 mm2. It is a...
