ABSTRACT:
A pulse generating circuit and related method, for producing extremely narrow pulses for use in monolithic microwave integrated circuits (MMICs) for radar, high-speed sampling, pulse radio and other applications. A sinusoidal input signal is supplied to two nonlinear shock wave generators, which are oppositely biased to produce periodic outputs that are mirror images of each other, one with a very steep rising edge and one with a very steep falling edge. The combined outputs would cancel each other completely but for the introduction of a slight time delay in one of them, which results in a narrow peak in the combined signals.
