Abstract
Current sources for bio-impedance measurements are limited by insufficient output impedance above 100 kHz. This paper presents a new current source, which achieves high output impedance (>1 MΩ at 1 MHz in simulation) to address this limitation. The current source has been designed in a 0.35-μm CMOS process and uses ±2.5 V power supplies. The circuit performance has been verified in simulation. © 2009 Springer-Verlag.
