چکیده :

In this paper, a modified power and data transmitter with high data rate to carrier frequency ratio (DRCF) is proposed for medical implants. The transmitter sends data and power through an inductive link which its primary coil is driven by a class-E power amplifier. The data rate is independent of the elements of the class-E power amplifier (especially RFC and the primary coil). Hence, the data rate can be increased up to the carrier frequency. In the previously proposed transmitter two different power supplies (main and auxiliary) are used. The auxiliary one delivers a negative power which should be transferred to the main power supply so that the saved power is reused. This complexity is solved in the proposed circuit. A proof-of-concept prototype of the proposed transmitter implemented on printed circuit board works at 1 MHz carrier frequency. The data rate is equal to 500 kbps. The power delivered to the load is 53 mW and the power efficiency is close to 58%.
