Abstract
A circuit for generating a sawtooth current (I) in a coil (25), the coil (25) being driven during the trace periods of the sawtooth from an amplifier circuit (4, 6, 7, 9, 15) by a current, and during the shortest possible retrace periods, the amplifier circuit being blocked, the coil (25) being included in a resonant circuit (25, 20, 21, 18, 7) which further comprises a capacitor (20), a first (21) and a second diode (18) and a transistor (7). In order to prevent disturbing ringing phenomena from occurring when a retrace period of the shortest possible duration is required, the junction of the capacitor (20), the first (21) and the second diode (18) and the transistor (7) is fed-back via a resistor (23) to a signal input of an amplifier (4) comprised in the amplifier circuit (4, 6, 7, 9, 15), this signal input further being coupled to a terminal (1) for the supply of a sawtooth voltage.
