ABSTRACT:
A resonant circuit arrangement is for generating an amplitude-shift-keyed and/or phase-shift-keyed signal. The resonant circuit arrangement includes a capacitive storage element having a first terminal and a second terminal. The first terminal is electrically connectable to a control voltage and the second terminal is electrically connected to a reference potential. The resonant circuit arrangement also includes an inductive storage element having a third terminal and a fourth terminal, where the third terminal is electrically connectable to the reference potential, a first switch for electrically connecting the fourth terminal to the reference potential, a second switch for electrically connecting the fourth terminal and the first terminal, and a control unit for driving the first and second switches based on transmission data.
