Abstract

The invention provides an amplitude increasing and width reducing circuit unit and a pulse signal generating circuit and generator comprising the amplitude increasing and width reducing circuit unit. According to the amplitude increasing and width reducing circuit unit, two avalanche transistors which are cascaded are used as a basic unit circuit to construct the nanosecond balance pulse signal generator, and compared with a pulse generating circuit composed of a single avalanche transistor, pulse signals generated by the nanosecond balance pulse signal generator are large in amplitude, the pulse front edges are steep, and circuit reliability is high.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a circuit unit for increasing amplitude and reducing width, and a pulse signal generating circuit and a generator using the same. Background technique [0002] Ultra-wideband technology is a wireless technology for data communication through sub-nanosecond or picosecond narrow pulse signals. It has high data transmission rate, high bandwidth, strong anti-multipath ability, low probability of being intercepted and detected, and positioning The advantages of high precision can be effectively applied to wireless local area networks, perspective imaging, precise positioning, non-destructive testing, medical systems (such as telemedicine services, non-contact detection of heartbeat and breathing), weapon control systems (such as anti-jamming confidential military communications, navigation , electronic countermeasures, large ordnance anti-collision, anti-terrorist combat) and othe...
