Abstract

The invention discloses a pulse rapid converter device and consists of a pulse rapid shaping circuit that is made of forward and reverse snap off diodes, one end of the parallel forward and reverse snap off diodes is a rapid pulse signal output end that is connected with the shaping pulse signals through a resistance; the other end is connected with the pulse DC biasing power source end. When the snap off diode enters the reverse and stops from the forward flow, since the effect of minority, the snap off diode has large reverse current. When the reverse current disperses the minority inside the diode, the time is tq, the current inside the diode rapidly develops toward reverse saturation current with the time of tt, thus, the voltage on the load maintains within the tq period while rapidly increase or decrease within the tt time. The ascending/descending time of the pulse is quickened by the property of snap off of the snap off diode, the time thereof equals to the reverse restoring time of the snap off diode so as to realize rapid shaping of the pulse.

Description

technical field [0001] The invention belongs to the technical field of high-speed pulse signal generation, and specifically relates to a pulse fast edge conversion device. Background technique [0002] High-speed pulse signal is the key factor of the test system, and it is widely used in various electronics-related industries such as communication, radar, semiconductor manufacturing, integrated circuit testing, microprocessor testing and geological exploration. At the same time, there is a great demand for high-speed pulse signal sources in ultra-wideband communication, radar, guidance, and oscilloscope calibration. [0003] With the rapid development of microelectronics technology and the widespread use of radio frequency circuits, the performance indicators of pulse signal sources required for system testing have also been continuously improved. High-speed pulse generation technology has gradually become the basis for the development and testing of many high-speed circuits...
