| 100 GHz Dynamic Frequency Divider in a SiGe Bipolar Technology |
| This letter reports a 100 GHz dynamic frequency divider and a 62 GHz static frequency divider, both using a -3.8 V supply and designed in IBM’s 0.12 µm SiGe technology with fT of 207 GHz and fMAX of 285 GHz. Static divider performance is compared to three other static dividers designed in IBM’s 0.18 µm SiGe BiCMOS technology.
