Abstract

Various embodiments relate to accelerating ramp-down of a modulated signal. In one embodiment, an antenna driver signal is defined and asserted to accelerate ramp-down. The accelerating ramp-down driver signal may include a series of sinusoidal-like pulses asserted at a driver output. The sinusoidal-like pulse may be synchronized by phase to a declining antenna current. Signal properties—such as phase, amplitude, delay, shape and frequency—of the sinusoidal-like pulse may be adopted to affect the ramp-down of the modulated signal.
