摘要
报道了由超薄基区负阻异质结双极晶体管(UTBNDRHBT)构成的非稳多谐振荡器,具有高速、可调控等优点。对其电压控制脉冲频率调制效应进行了实验研究,观察到了仅由基极电压(V_(BE))即可控制脉冲间距和脉冲宽度;对实验现象给出了相应分析,并指出了此电路的应用前景。
This paper has reported the astable multivibrator composed of negative differential resistance heterojunction bipolar transistor with ultrathin base （UTBNDRHBT）. The astable multivibrator composed of UTBNDRHBT has the advantage of high speed and frequency modulation. In experiment, the voltage controlled pulse frequency modulation has been studied, and we observed that the pulse interval and pulse width can be controlled by the voltage of base（VBE） only. In the paper, the experimental phenomena on astable multiviberator have been described, analyzed and explained. In addition, the application prospect of this device has been expected.
