“…Static frequency dividers are able to offer robust operation over a wide frequency range, playing a critical role in various microwave applications such as quadrature signal generation [1,2,3], phase-locked loop (PLL) [4,5], clock and data recovery (CDR) [6], time-interleaved analog-to-digital converter (ADC) systems [7,8] and other wireless communication fields [9,10]. Applications above generally require frequency division in wide operating bandwidth and at a relatively high rate as their performance continues to evolve, putting forward demands for the design and fabrication of high-speed broadband static frequency dividers.…”
