  • Elimination of crosstalk in two sequentially operated Darlington amplifier channels
    Patent number: 4017743
    Abstract: Discrete logic circuit crosstalk in two sequentially-split pulse Darlington mplifier channels is eliminated by the use of diodes connected between the stages of the amplifiers so as to clamp the non-operating amplifier to ground condition. Also transistors may connect the non-operating amplifier to ground conditions so as to eliminate any unwanted pulses.
