Abstract

The invention provides a generation method and circuit device of fast high-current pulse current with adjustable pulse width, amplitude and intra-pulse slope, which are suitable for load-grounded current pulse output conditions having the characteristics of high power, fast rising edge, adjustable intra-pulse slope and the like. The circuit device comprises a direct current power supply, a pulse generation device, a fast rising edge driving circuit, a slope adjusting circuit and a pulse current output circuit. Finally, a high-current pulse with the fast rising edge and the adjustable pulse width, amplitude and intra-pulse slope is generated. Therefore, requirements of excitation pulses in an impact avalanche and transit time (IMPATT) diode oscillation device are met.

Description

technical field [0001] The invention relates to the technical field of pulse excitation, in particular to a fast and high-power pulse current generation method and a circuit device with adjustable pulse width, amplitude and pulse slope. Background technique [0002] With the breakthrough and progress of components and technology levels, millimeter wave power transceiver devices based on IMPATT (Impact Avalanche and Transit Time) diodes are developing very rapidly, and are widely used in various systems such as radar, communication and precision guidance. . Among them, the IMPATT diode pulse oscillator is one of the key devices, and its performance directly affects the performance of the entire system. The IMPATT diode as a load has high requirements on the excitation current pulse: under the premise of grounding itself, the rising edge of the pulse is required to be less than 10ns, and the pulse width is adjustable within the range of 100±50ns, and it needs to have sufficie...
