Embodiments of the disclosure relate to a low-power, high-data-rate, radio transceiver inside a contact lens. The radio transceiver includes a phase-locked loop having a frequency acquisition loop that turns on and off based on various performance characteristics of the transceiver. The transceiver also includes wireless power harvesting circuitry that receives a wireless power signal and generates a reference signal that is used by an oscillator within the transceiver.
