Tunable and switchable film bulk acoustic resonators (FBARs) with the capability of
dynamically adjusting their resonant frequencies hold significant promise for advanced multi …

A CMOS phase noise filter (PNF) enabled by the passive delay line (DL) and phase
detector/charge pump (PD/CP) based frequency discriminator is proposed. The delay …

This paper presents a delay line frequency discriminator and phase detector/charge pump
(PD/CP)-based phase noise measurement (PNM) circuit with wide bandwidth, great …

This brief presents a feedforward phase noise cancellation technique to reduce phase noise
of the output clock signal of a phase-locked loop (PLL). It uses a sub-sampling phase …

In this paper, we present a bang-bang phase detector (BBPD) and a delay-line frequency
discriminator-based phase noise filter (PNF). With a larger phase detection gain, the BBPD …

Two techniques for spur and phase noise cancellation have been proposed. A fully
integrated design achieves a measured spur cancellation of 15dB at 250MHz and 750MHz …

This paper presents a phase noise filter technique enabled by the delay-line and PD/CP
based frequency discriminator with fully automatic calibration. It features wide bandwidth …

In this article, we present a new phase noise reduction structure for oscillators based on a
six-port frequency discriminator (FD) using a multiplexer. In general, the FD for oscillators …

This paper demonstrates a phase noise improvement technique for array systems by using
the phase noise filter (PNF) and the noise's uncorrelated feature. The PNF aims to suppress …
