This paper analyses the noise performances of coupled phase-locked loops, providing closed-form expressions for the transfer functions of the various noise sources, and presents a novel coupling topology, whose goal is the reduction of both in-band a

The advent of the next-generation wireless communication standards demands increasingly faster transceivers, posing extremely challenging requirements on the frequency-synthesizer integrated jitter [1, 2]. As demonstrated in [1], the bang-bang digita

This work introduces a bang-bang fractional-N phase-locked loop with quantization noise shaping that overcomes the classical noise limit of a standard bang-bang phase detector. An adaptive algorithm, working in the background of the main system, guar

This work presents a novel architecture of frequency synthesizer which allows to easily couple two digital PLLs (synchronized to the same reference source) and scale phase noise and power consumption. The second-harmonic component of the two digital

This paper analyzes the absolute jitter performance of digital phase-locked loops and compares the case when either a multi-bit time-to-digital converter with mid-rise characteristic or a bang-bang phase detector is adopted. The linear equivalent mod

Digital phase-locked loops (DPLLs) have been demonstrated to achieve excellent performance as fractional-N frequency synthesizers in the sub-6GHz range, but, when used in the mm-wave range, at 30GHz and above, they typically feature poor jitter-power

This article describes the implementation of a 30-GHz frequency synthesizer. The target is to reduce the gap in terms of jitter-power product that exists between millimeter-wave and RF synthesizers, using a low-cost 65-nm LP CMOS technology. The circ
