Abstract :
This paper presents an implantable integrated FM transmitter using 0.35 μm SiGe process for biotelemetry. The architecture of FM transmitter is based on the Colpitts oscillator, which is followed by a buffer amplifier to isolate the influence of output on the resonant frequency of the oscillator. The chip area of the fabricated FM transmitter is only 0.26 mm2. Even without an intentional antenna, the experimental results show that electrocardiograms (ECGs) of a rat using the FM transmitter can be successfully transmitted to a personal computer, where the heart rate variability (HRV) is analyzed.
