The implanted biomedical devices require very efficient RF-DC rectified signal, which provides the essential DC voltage, delivered to the implanted device. In this paper, a switch-only rectifier based on CMOS switch controlled by a timing control circuit is used to improve the rectified signal. This rectifier is used instead of the conventional rectifiers such as Full-bridge rectifier, voltage doublers...
This paper introduces a modified an efficient design for different Class-E power amplifiers suitable to be use in biomedical implantable devices and in biomedical wireless telemetry devices which is usually have a small load resistor (several Ohms) due to its inductive powering. The different Class-E amplifiers operated according to the frequency chart for the medical implant communications service...
