Abstract
A method and apparatus with adaptive transponder plucking is provided in which oscillations from a resonant circuit (12 and 14) are maintained by coupling power from a capacitor (18) through a switch (26) to the resonant circuit (12 and 14). The switch (26) is controlled by adaptive pluck circuitry. The adaptive pluck circuitry includes peak level detector (22) and comparator (24). When the peak level of an oscillating signal from the resonant circuit (12 and 14) falls below a reference voltage, the switch (26) is activated to couple power to the resonant circuit (12 and 14).
