  • Circuit for compensating rise times and ringing in high impedance loads
    Patent number: 7122999
    Abstract: Circuits for shortening a rise time of a load include a main pulse transformer coupled to a load, an auxiliary pulse transformer coupled to the load, and a diode connected between the auxiliary pulse transformer and the main pulse transformer. The main pulse transformer delivers a main pulse to the load. The auxiliary pulse transformer delivers an auxiliary pulse to charge the capacitance associated with the load. The diode isolates the auxiliary pulse transformer from the main pulse. By charging the capacitance in this manner, a rise time of the main pulse is shortened and ringing of the main pulse on the load is reduced.
