Definitions
- the present invention provides a simple and efficient narrow pulse generating circuit for a sequential equivalent sampling system.
- the edge sharpening circuit includes a resistor R1, a capacitor C1, a resistor two R2, a step recovery diode SRD, a capacitor two C2, and a resistor six R6, wherein the resistor one R1, capacitor one C1, capacitor two C2, and resistor Six R6, the negative pole of the power supply are connected in sequence, one end of the crystal oscillator is grounded, and the other end is connected to a resistor R1; and one end of the step recovery diode SRD is connected to the ground, and the other end is connected between capacitor C1 and capacitor C2, the resistor
- the two R2 terminals have a positive power source at one end, and the other end is connected between capacitor C1 and capacitor C2.
- the output pulse waveform of the Schottky diode is used for interception. Because the reverse-cutoff time of a Schottky diode is very short, it only takes tens of picoseconds from the forward-conduction time to the reverse-cutoff time. Therefore, it can be used to pass signals higher than the threshold voltage, which is determined by V d .
- the RC network function is added in the subsequent stage according to the pulse width.
- the RC shaping network consists of a coupling capacitor C C and a load resistor R L.
- the narrow pulse circuit of the invention has a simple structure and a narrow pulse width at the bottom, which is beneficial to improving the signal-to-noise ratio of the entire sequential sampling system.
