Abstract
A miniature, implantable, remote RF powering system for a small, un-tethered laboratory animal inside a cage is proposed. The proposed implantable device exhibits dimensions 6 mm x 6 mm x 2 mm and a mass of 100 mg including bio-compatible silicone coating. The external system consists of a Class-E power amplifier driving a tuned 15 cm x 25 cm coil. The implant device includes integrated “capacitor-free” RF to DC and power control circuitry. The full system provides 2 V VDD at up to 1 mA to implant electronics with < 200 μV DC variation, < 1 mV total RMS noise, and < 25 mVpp 4 MHz ripple and a 3 V supply to CMOS switches over a 10 cm x 20 cm operating region with an implant tilt angle of up to 60°. Additionally, an intelligent power control system is proposed that would reduce external system power consumption and cage temperature increase.
