A high-speed broadband programmable frequency divider chip is designed and implemented in 0.18 μm SiGe BiCMOS process. The chip is based on the 2/3 dual-mode frequency divider, and integrates high-speed logic operation and reset control in the flip-flop to achieve a wide range of continuous integer frequency division ratio. Taking SCFL and CML DFF as basic units, it realizes wideband operation and obtains a good input sensitivity range. The test results demonstrate that the operating frequency covers 0.1 GHz to 16 GHz. The frequency divider achieves 1-511 continuous frequency division. The output signal phase noise of the 1 GHz input is -153.7 dBc/Hz @ 100 kHz offset in divide-by-8 mode.
