Integrated circuit for wireless inductive powering implemented in 180nm CMOS process.

Our report is on the simulation results and the design of the integrated circuit dedicated for inductive powering of a neural recording system on a chip. Four different voltage rectifiers were considered. designed to compare their power efficiency, drop out voltages, and ability to work in a megahertz range. Each of the full bridge rectifiers is equipped with voltage clamps to prevent it from the high coil voltages. Presented circuits are dedicated for carrier signals in the range of a few MHz and load current of 10mA. Performance of the circuits is discussed based on the post-layout simulations. The circuit was designed in 180nm CMOS process and sent to fabrication. [ABSTRACT FROM PUBLISHER]
