    • A radio frequency identification tag includes an antenna terminal, a memory, a D/A converter, a clock extractor, a frequency synthesizer, a radio frequency UP converter, and a power unit. An energy pumping signal is received and tag identification information is transmitted through the antenna terminal. The tag identification information is stored in the memory. The D/A converter converts the tag identification information into an analog signal in response to an information request signal included in the energy pumping signal. The clock extractor extracts a clock signal from the energy pumping signal. The frequency synthesizer is operated according to the clock signal of the clock extractor, and generates a frequency. The radio frequency up converter up-converts a signal output from the D/A converter, and allows the up-converted signal to be transmitted through the antenna terminal. The power unit supplies internal power.

    • Apparatus and methods for detecting a lock in a phase-locked loop (PLL) are disclosed. In one aspect, a lock detect component includes a reference multiplier and a lock detect. The reference multiplier can receive a reference signal, a divider signal, and a voltage-controlled oscillator (VCO) output generated by a VCO in a PLL from which the divider signal is generated. The reference multiplier can also generate a multiplied reference signal using the reference signal and the VCO output. The multiplied reference signal can have a frequency that is an integer multiple of a frequency of the reference signal. The lock detect can detect a phase lock of the reference signal and the divider signal based at least in part on comparing a signal generated from a delayed reference signal and a signal generated from a delayed divider signal for a predetermined period of time.
