摘要

给出了电流模式逻辑(CML)环形振荡器在液氮温度下的性能实测数据。采用双聚双极技术制备器件和电路。用混合pi模型对实验数据进行了解释。采用1.0 μ m设计规则制作CML环形振荡器。在LN/sub 2/处测量到的延迟比室温时增加了2.3倍。延迟的增加可以用基极电阻和负载电阻的温度行为来解释。

Switching characteristics of poly bipolar circuits at liquid nitrogen temperature

Measured data are presented on performance of current mode logic (CML) ring oscillators at liquid nitrogen temperature. The devices and circuits were fabricated using double-poly bipolar technology. The experimental data are explained using the hybrid- pi model. CML ring oscillators were fabricated using 1.0 mu m design rules. The measured delay at LN/sub 2/ increased by a factor of 2.3 compared to that at room temperature. The increase in delay is explained by the temperature behavior of the base and load resistors.<>
