Résumé
Designing electrical impedance spectroscopy systems is driven by target applications. Moreover, system blocks are interdependent. Thus, optimizing the design of each block without input from the others is impossible. Furthermore, simulating the whole system at transistor level is time-consuming. This publication presents a mixed-level simulation tool for the efficient development of bioimpedance spectroscopy measurement systems. We develop Verilog-AMS models combined with transistorlevel descriptions of several analog blocks. This allows us to run highly efficient system-level simulations for a whole circuit. We apply this tool to the design of an integrated circuit suitable for in-vivo monitoring of Bluefin Tuna physiological parameters.
