1. A transponder, comprising:

  • a rectifier;

    an oscillator configured for squegging to stop oscillations before the oscillator reaches steady state operation;

    a hysteretic switch coupled between the rectifier and the oscillator, wherein the hysteretic switch is operative to selectively switch scavenged power to the oscillator, and a turn-on transient period exists after power is applied to the oscillator; and

    a radiative structure coupled both to the rectifier and the oscillator.
