Low power current sources for bioimpedance measurements: a comparison between Howland and OTA-based CMOS circuits
Multifrequency Electrical Bioimpedance (MEB) has been widely used as a non-invasive technique for characterizing tissues. Most MEB systems use wideband current sources for injecting current and instrumentation amplifiers for measuring the resultant potential difference. To be viable current sources...
