Low power consumption and efficient power supply are very crucial for biomedical implant electronics. The power issues in the design of implanted devices are addressed and three distinct design cases, including a low power stimulator chip for retinal prosthesis, a novel cochlear implant system with multi-level power optimization and a wireless monitoring system of total knee replacement, are demonstrated. All these cases focus on both reducing the power dissipation and raising the power supply efficiency at the aspect of circuit design. Besides, the future development of implantable electronic devices is also discussed based on the design practice.
