InP基共振隧穿二极管太赫兹振荡器的设计与实现
Design and realization of InP-based resonant tunneling diode THz oscillator
摘要
Abstract
An oscillator above 1 THz is designed and realized using InP-based resonant tunneling diode(RTD) and an on-chip antenna with Si-lens. The RTD model was built and studied with Silvaco software. The influences of the doping concentration of emitter,the thickness of barrier layer,space layer,and well layer on the DC char?acteristics of the device have been analyzed. The DC measurement of the RTD shows the peak current density Jp=359. 2 kA/cm2,the valley current density Jv = 135. 8 kA/cm2,and the peak-to-valley current ratio(PVCR)=2. 64. According to the measurement,the maximum RF output power and oscillation frequency(fmax)are theoreti?cally calculated,which are 1. 71 mW and 1. 49 THz,respectively. The oscillator with an on-chip bow-tie antenna and RTD is packaged with Si-lens. The measurement shows the output power is 2. 57 μW at an operation frequen?cy of above 1 THz,the DC power consumption is 8. 33 mW. This is the first reported oscillator of frequency above 1 THz in domestic.关键词
