Abstract :
A performed dual band telemetry system with a DPSK data modulation scheme is reported for inductively powered biomedical implants. The innovation of this system consists on improving data rates with a novel full digital DPSK demodulator that achieves a data-rate-to-carrier-frequency ratio of 100% and a power consumption of 136.3μW @ 3.3 V at a data transmission rate of 10 Mbps. The whole receiver was designed with the 0.35-μm CMOS technology of Austria Micro Systems.
