Full-dimension MIMO (FD-MIMO) using planar active antenna systems (AAS) is considered a critical technology for fifth-generation (5G) cellular systems to improve network capacity. An AAS is typically subject to hardware impairments that negatively im

Massive multiple-input and multiple-output (MIMO) has been the subject of interest in both industry and academia for the past few years. Massive MIMO refers to the use of a large number of antennas typically at the base station (BS) to serve multiple

Although multiplying delay-locked loops allow clock frequency multiplication with very low phase noise and jitter, their application has been so far limited to integer-N multiplication, and the achieved reference-spur performance has been typically l

Digital fractional-N phase-locked loops (PLLs) are an attractive alternative to analog PLLs in the design of frequency synthesizers for wireless applications. However, the main obstacle to their full acceptance in the wireless-systems arena is their

This paper introduces a ΔΣ fractional-N digital PLL based on a single-bit TDC. A digital-to-time converter, placed in the feedback path, cancels out the quantization noise introduced by the dithering of the frequency divider modulus and permits to

The bandwidth of a phased-locked loop (PLL) is dependent on several analog parameters that are subject to process, temperature and voltage spreads, as well as to variations along the frequency-tuning range. Even in digital PLLs, which rely on a digit

The introduction of inductorless frequency synthesizers into standardized wireless systems still requires a high level of innovation in order to achieve the stringent requirements of low noise and low power consumption. Synthesizers based on the so-c
