双向负阻晶体管(BNRT)是辽宁朝阳无线电元件厂和中国科学院半导体研究所合作制成的一种新功能器件.用BNRT实现的一些自激脉冲振荡电路,结构简单、能够产生幅度大于2V(50Ω负载)的毫微秒脉冲而只用低压电源供电,这是其它负阻器件不易实现的.本文介绍几个简单的实验电路,它们有可能应用在各种脉冲电路中.图1为负脉冲自激振荡电路,当E_c调到+15V以
The bidirectional negative resistance transistor (BNRT) is a new functional device made by Liaoning Chaoyang Radio Components Factory and the Institute of Semiconductors, Chinese Academy of Sciences Some self-excited pulse oscillation circuits realized by BNRT have a simple structure and can generate amplitudes greater than 2V (50Ω Load) of the nanosecond pulse and only low-voltage power supply, which is difficult to achieve other negative resistance devices.This article describes a few simple experimental circuits, they may be used in a variety of pulse circuits.Figure 1 shows the negative pulse from Oscillation circuit, when E_c transferred to +15 V
