Description Non-invasive, continuous-time monitoring of metabolites, biomarkers, drugs and pathogens by wearable biosensensors is required to identify the source and to track the evolution of diseases, to enhance the effectiveness of therapies and to significantly improve the quality of life of patients.
Next generation electrochemical biosensors for wearable devices need to be extremely small, low cost and suitable to operate under an extremely low, possible variable power budget, as available from mm-scale energy harvesters. Such requirements are extremely challenging to meet by traditional opamp-based sensor readout electronics based on traditional analog design techniques, thus motivating a constantly increasing research interest towards radically new design approaches.
In thif framework, the thesis is focused on the design, optimization, verification and silicon implementation of a novel-in-concept, digital-based, ultra-low power potentiostat readout integrated circuit in 130nm CMOS.
