Electronic design for an implantable wireless power and data transmission system

This design presents electronic design for an implantable wireless power and data transmission system with an inductive link designed for bio-sensor signal sensing. The system consists of an external module and an implantable module which includes a power regulator, a pressure sensor and a data transmitter. This paper puts forward a detailed design of the inductive link and two important blocks of the internal module-preamplifier and filter. The designed circuits are implemented in 0.5-um 2P3M standard CMOS process.
