In this work, a dual-mode (divide-by-2 and divide-by-3) dynamic frequency divider is presented. A tunable delay gated ring oscillator (TDGRO) topology is proposed for dual-mode operation and bandwidth extension. It uses a 130-nm gate length SiGe BiCMOS technology with the $f_{t}$ and $f_{\mathrm {max}}$ of 250 and 370 GHz, respectively. Verification shows that it works at $W$ -band from 70 to 114 GHz (47.8% bandwidth) for divide-by-2 and works at $D$ -band from 105 to 160 GHz (41.5% bandwidth) for divide-by-3. This divider can be used in integrated phase-locked loops (PLLs) at millimeter-wave frequencies.

采用 130 纳米 SiGe 技术的 D 波段双模动态分频器

在这项工作中，提出了一种双模式（除以 2 和除以 3）动态分频器。可调谐延迟门控环形振荡器 (TDGRO) 拓扑被提议用于双模式操作和带宽扩展。它使用 130 nm 栅极长度的 SiGe BiCMOS 技术，具有 $f_{t}$ 和 $f_{\mathrm {max}}$ 分别为 250 和 370 GHz。验证表明它在 $W$ - 频带从 70 到 114 GHz（47.8% 带宽）用于除以 2 并在 $D$ - 频带从 105 到 160 GHz（41.5% 带宽），用于除以 3。该分频器可用于毫米波频率的集成锁相环 (PLL)。
