Abstract

The ability to accurately model and simulate the behaviour of test devices is essential for effective design of sensor interface circuits. Electrochemical sensors are becoming increasingly popular for environmental and biosensing applications, generating a demand for high-performance and low-power sensor interfaces. Such sensors exhibit non-linear behaviour with non-negligible memory effects, and hence are difficult to model using standard electronic components in circuit simulation frameworks. Working toward overcoming this limitation, a Verilog-A-based model of a typical three-electrode electrochemical sensor has been developed and is presented. The model simulates electrochemical kinetics and mass transport effects in the time domain, outputting a redox current as a response to a provided electrode potential.
