  • Transistor amplifier for generating complementary trapezoidal waveforms
    Patent number: 3991325
    Abstract: A transmission line amplifier for generating substantially identical complementary trapezoidal output waveforms for a twisted pair transmission line thereby reducing cross-talk on the twisted pair lines. Current summing means and a capacitor are used to insure that when the capacitor is midway through its discharge-charge cycle, the two output currents are at the midpoint of their transition stage and are equal whereby the sum of the complementary trapezoidal output waveforms is constant.
