Due to various inherent complications in wired brain implants, there has been a growing need for development of a wireless channel selector to precisely select multiple stimulation electrodes to provide simultaneous stimulations to the motor cortex and monitor its response to the stimulations. This thesis presents Complementary MOSFET (CMOS) design of a pre-developed and patented wireless-battery free channel selector to precisely select multiple regions in the motor cortex for simultaneous stimulation and recording. It maintains the functionality of the original work, while achieving better data transmission rates, smaller current consumption and smaller area.
