摘要

介绍了一种基于多阱谐振隧穿二极管(RTD)的新型模数转换器。通过使用rtd，可以降低A/D电路的复杂度。作者模拟了一个4位a /D转换器在30 ghz频率下对三角波进行数字化处理的性能。结果表明，与最先进的闪存A/ d相比，该方法有望大大提高速度，降低电路复杂性和功耗。面包板电路和SPICE3仿真的结果非常令人鼓舞。

A/D converter using InGaAs/InAlAs resonant-tunneling diodes

A novel A/D (analog/digital) converter based on the multiwell resonant-tunneling diode (RTD) is described. By using RTDs, the A/D circuit complexity can be reduced. The authors simulated the performance of a 4-bit A/D converter digitizing a triangular wave with the digital output changing at a 30-GHz rate. The results show that the approach holds the promise of greatly increased speed and reduced circuit complexity and power in comparison to state-of-the-art flash A/Ds. The results from breadboard circuits and SPICE3 simulations are very encouraging.<>
