@article{(Open Science Index):https://publications.waset.org/pdf/5528, title = {An Inductive Coupling Based CMOS Wireless Powering Link for Implantable Biomedical Applications}, author = {Lei Yao and Jia Hao Cheong and Rui-Feng Xue and Minkyu Je}, country = {}, institution = {}, abstract = {A closed-loop controlled wireless power transmission circuit block for implantable biomedical applications is described in this paper. The circuit consists of one front-end rectifier, power management sub-block including bandgap reference and low drop-out regulators (LDOs) as well as transmission power detection / feedback circuits. Simulation result shows that the front-end rectifier achieves 80% power efficiency with 750-mV single-end peak-to-peak input voltage and 1.28-V output voltage under load current of 4 mA. The power management block can supply 1.8mA average load current under 1V consuming only 12μW power, which is equivalent to 99.3% power efficiency. The wireless power transmission block described in this paper achieves a maximum power efficiency of 80%. The wireless power transmission circuit block is designed and implemented using UMC 65-nm CMOS/RF process. It occupies 1 mm × 1.2 mm silicon area. }, journal = {International Journal of Electronics and Communication Engineering}, volume = {6}, number = {9}, year = {2012}, pages = {931 - 934}, ee = {https://publications.waset.org/pdf/5528}, url = {https://publications.waset.org/vol/69}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 69, 2012}, }
