@inproceedings{24354, abstract = {{In this paper, a 6-bit true modular programmable frequency divider with division ratios ranging from 64 to 127 is reported. It is composed of a divider chain of 6 divide-by-2/3 cells, and ECL stages that are introduced as synchronization circuits for programming inputs. The synchronization circuits have CMOS input for compatibility with programming circuits. The stand-alone divider chain is functional up to an input clock frequency of 49 GHz. The combination of the divider chain with synchronization circuits is functional up to 44 GHz. The 6 stage divider draws 34 mA current from a 2.7 V supply. The synchronization circuits draw 30 mA from a 3 V supply. The circuit is fabricated in a 0.13 μm SiGe BiCMOS technology, and is well suited for millimeter-wave phase-locked loop (PLL) circuits which require fine frequency resolution.}}, author = {{Ergintav, Arzu and Sun, Yaoming and Scheytt, Christoph and Gürbüz, Yasar}}, booktitle = {{Silicon Monolithic Integrated Circuits in RF Systems (SiRF), 2013 IEEE 13th Topical Meeting on}}, title = {{{49 GHz 6-bit programmable divider in SiGe BiCMOS}}}, doi = {{10.1109/SiRF.2013.6489451}}, year = {{2013}}, }
