摘要

本文研究了磁场对工作在w波段(75 ~ 110 GHz)的双漂移区(DDR)冲击雪崩传递时间(IMPATT)器件噪声性能的影响。横向磁场作用下的反向偏置DDR IMPATT结构可视为磁场可调雪崩传递时间(MAGTATT)器件。仿真结果表明，当器件保持在横向磁场中时，器件的噪声谱密度和噪声量均有显著增加。当磁场的大小增加时，器件的噪声性能的这种退化会增强。因此，为了实现作者先前报道的DDR IMPATTs射频特性的磁场调谐，必须在相当程度上牺牲源的噪声性能。

Avalanche noise in magnetic field tunable avalanche transit time device

Influences of magnetic field on the noise performance of double-drift region (DDR) impact avalanche transit time (IMPATT) device based on Si designed to operate within W-band (75–110 GHz) have been studied in this paper. The reverse biased DDR IMPATT structure under transverse magnetic field can be regarded as magnetic field tunable avalanche transit time (MAGTATT) device. The simulation results show that both the noise spectral density and noise measure of the device increase significantly while the device is kept in transverse magnetic field. This degradation of the noise performance of the device enhances when the magnitude of the magnetic field is increased. Therefore, in order to achieve the magnetic field tuning of the RF properties of DDR IMPATTs as reported earlier by the authors, the noise performance of the source has to be sacrificed in fair extent.
