Abstract :
Using the reflected impedance property of an inductive couple (transformer), a modulation method, load-shift keying using circuit configuration modulator (LSK-CCM), was developed to perform data transmission from an implantable telemeter. With a very simple circuit, this method utilizes a radio-frequency electromagnetic field induced with a single pair of coils to transmit power into the implant and data out of it
