  • Narrow pulse generation circuit used in sequential equivalent sampling system
    Patent number: 11309871
    Abstract: A narrow pulse generation circuit used in a sequential equivalent sampling system. The circuit comprises a crystal oscillator, an edge sharpening circuit, an avalanche transistor single-tube amplifying circuit and a shaping network connected in sequence, wherein the edge sharpening circuit is used for carrying out edge sharpening on a square wave signal generated by the crystal oscillator; the avalanche transistor single-tube amplifying circuit is used for carrying out avalanche amplification on the sharpened square wave signal to generate a Gaussian pulse signal to adjust the amplitude of a pulse; and the RC shaping network is used for shaping the Gaussian pulse signal to adjust the pulse width at the bottom of the pulse to form a narrow pulse signal. The narrow pulse circuit has a simple structure and narrow pulse width at the bottom and facilitates increasing a signal-to-noise ratio of a whole sequential sampling system.
