1. A circuit operative to modulate oscillation frequency of a transmit signal, the circuit comprising:

  • a control block adapted to dynamically modulate a generated signal;

    a filter adapted to modify a biasing voltage applied to a first terminal of a transistor in response to variations in the generated voltage signal; and

    a pulse generator adapted to generate a pulse signal in response to detection of a transition of an oscillating signal;

    said transistor adapted to generate a radio frequency signal in response to receipt of a low-to-high or high-to-low transition of the generated pulse.
