In this tutorial brief, we introduce a unified wideband phase-noise theory framework of
frequency synthesis based on a multirate timestamp modeling with “two-variables”. We …

In this article, we present a low phase noise (PN) mm-wave quadrature digitally controlled
oscillator (DCO) exploiting transformers for class-F operation and harmonic extraction. A …

Fast settling phase locked loops (PLLs) play a pivotal role in many applications requiring
rapid attainment of a stable frequency and phase. In modern communication standards …

In this article, we propose a digital-to-time conversion technique operating entirely in the
sinusoidal waveform voltage domain of a crystal oscillator (XO) before the signal's final …

This article presents a wide-band suppression technique of flicker phase noise (PN) by
means of a gate–drain phase shift in a transformer-based complementary oscillator. We …

This article proposes a mm-wave fractional-N ADPLL employing a reference-waveform
oversampling (ROS) phase detector (PD) that increases its effective rate four times …

In this paper, we propose a digital-to-time conversion (DTC) technique operating entirely in
the sinusiodal waveform voltage domain of a crystal oscillator (XO) before the signal's final …

In this paper, we prove that rather than the second-order Δ Σ modulator (DSM) as typically
believed using the first-order one yields a faster convergence for the linear-piecewise …

In this paper, we propose a two-step time-to-digital converter (TDC) using gated delay
technique to reduce power consumption. To reduce power consumption gated delay …

This paper aims to intuitively explain and numerically verify the locking range of a sub-
harmonic injection-locked oscillator (ILO) when applying different injection multiplying ratios …
