4.4-5.3 GHz All-Digital Frequency Synthesizer for Cryogenic Applications

A 4.5G~5.4GHz digital bang-bang PLL for 77K cryogenic applications. The digital approach overcomes the design challenges that arise from a wide temperature operation range. The implicit common-mode resonance in the DCO suppresses flicker noise up-conversion. The application areas include quantum computing, superconducting applications, and more.
