本文介绍了一种采用0.13μm SiGe BiCMOS工艺设计的全集成D波段真时间延迟(TTD)电路。在110 ~ 170 GHz范围内,相对时延为0.446 ps ~ 6.64 ps,分辨率为0.446 ps,相当于4位移相器的精度。所提出的真正的时间延迟IC占地2.2 mm x 0.53 mm,从3.3 V汲取6.92 mA的电流。据我们所知,这是第一个真正的时间延迟电路超过100 GHz的硅技术与创纪录的3 dB带宽为60 GHz。
This paper presents a fully integrated D-band true time delay (TTD) circuit designed in 0.13µm silicon-germanium (SiGe) BiCMOS technology. It provides a relative time delay of 0.446 ps to 6.64 ps from 110 to 170 GHz with the resolution of 0.446 ps equivalent to the accuracy of a 4-bit phase shifter. The presented true time delay IC occupies 2.2 mm x 0.53 mm and draws a current of 6.92 mA from 3.3 V. To our knowledge, it is the first true time delay circuit above 100 GHz in silicon technology with a record 3-dB bandwidth of 60 GHz.
