This RF front-end circuitry is designed for clock and data extraction from wirelessly transmitted RF pulses for use in controlling the resonance of an implantable receiver coil with a digitally controlled capacitor array intended for monitoring an implanted artificial pancreas. The fabricated chip measures 650um by 450um and demonstrates the capability of data/clock recovery. The design is compatible with current NMR console technology and can be further integrated for in vivo operation.
