Abstract :
This paper presents a new analytical, empirical and behavioral modular model developed for accurate evaluation of power dissipation in power conversion chains (PCC) dedicated to power up an electronic implantable device. The model is suitable for power estimation/planning in early design stages, to determine the contribution of each circuit module on the total power consumption and to estimate the input and output voltages of these modules. It is based on average power consumption model and is coded in Verilog-A. The model is verified and the results were found to be in good agreement with state-of-the-art designs for bioelectronics devices. It is flexible and robust to changes in architecture and design parameters and provides accurate and valid results in a fraction of second for a large variety of parameter values. The ease of implementing desired modules and architectures makes the model more advantageous
