Problems solved by technology

Obviously, at this time, the traditional voltage equalization and current equalization scheme (such as parallel voltage equalizing resistors, etc.) can no longer meet the needs of circuit design, otherwise it will easily cause picosecond pulses to be distorted by refraction and reflection at various positions in the medium

Abstract

The invention provides a Marx circuit high-frequency high-voltage picosecond pulse generator with an avalanche triode series-parallel structure and application of the Marx circuit high-frequency high-voltage picosecond pulse generator. A power supply end is connected with one end of an R11 resistor and one end of an Rn1 resistor. The other end of the R11 resistor is connected with a collector of afirst avalanche triode group and one end of a C1 capacitor. A base of a first avalanche triode group is connected with a pulse signal output end. An emitter of the first avalanche triode group is grounded; the other end of the C1 capacitor is connected with the base of the second avalanche triode group. The emitter of the second avalanche triode group is connected with one end of an R12 resistor,and the other end of the R31 resistor is connected with the collector of a third avalanche triode group and one end of a Cn-1 capacitor; one end of the Rn1 resistor is connected with one end of the R31 resistor, the other end of the Rn1 resistor is connected with one end of the Cn capacitor and the collector of the nth avalanche triode group, the emitter of the nth avalanche triode group is connected with one end of the R (n-1) 2 resistor, and the other end of the R (n-1) 2 resistor is connected with the other end of the R22 resistor. The picosecond pulse generator is applied to a Marx circuit, so that the output picosecond pulse amplitude is improved.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a Marx circuit high-frequency and high-voltage picosecond pulse generator adopting an avalanche triode serial-parallel structure and its application. Background technique [0002] Picosecond pulses have attracted extensive attention from researchers at home and abroad because of their excellent properties such as rich ultra-wideband spectrum, high temporal and spatial resolution, small signal distortion, excellent directivity and fine controllability. Therefore, it is widely used in many technical fields such as detection radar, biomedicine, low-temperature plasma, food safety, sewage treatment, and high-power microwave. As the device basis for all research, it is imminent to develop a picosecond pulse generator that is all-solid-state, compact, miniaturized, and has high repetition rate, high stability, long life, convenient operation, and economical applicability. Among them...
