Abstract [en]

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 Omega to 1 M Omega. The SG is implemented in a 0.18-mu m CMOS process, it is powered by a single 1.8 V voltage source, and occupies a total area of 1.62 mm(2). It is able to generate single-frequency signals from 1 kHz to 2 MHz in 12 steps logarithmically spaced. High signal purity is achieved by using a second-order low-pass filter, with a bandwidth that can be programmed from 4 kHz to 8 MHz, in 12 points logarithmically spaced. The SG's power consumption varies from 750 mu W, at the lowest frequencies and gain, to 2.06 mW at the highest frequencies and gain. The output current levels can be modified from 130 nA up to 10 mu A in five programmable steps (9.5 dB per step). The SG achieves a spurious-free dynamic range larger than 40 dB while covering almost three decades in frequency. Such performance enables measurements with errors below 1%, as it is required for accurate bioimpedance measurements in many medical applications.
