Intracranial hemorrhage is associated with high mortality and morbidity. Lowering systolic blood pressure (SBP) with an intravenous antihypertensive, such as nicardipine or clevidipine, may reduce the risk of hematoma expansion and rebleeding. Previo

In this letter, we propose a 32–42-GHz frequency quadrupler that performs digital logic operations between four phase-shifted differential signals at one-fourth of the output frequency. The four phase-shifted signals are generated via a 10-GHz rota

Fractional-N frequency synthesizers that use a digital Δ-Σ modulator (DDSM) to control the feedback divider can exhibit spurious tones that move about in the frequency domain; these are known colloquially as ``walking'' or wandering spurs. Building

Apart from the well-known nonlinearity-induced fixed spurs, a DDSM divider-based fractional- $N$ frequency synthesizer can manifest spurs with time-varying frequency offsets from the carrier; these are called wandering spurs. This paper presents expe

This work presents a metamaterial structure to improve the isolation between two linear slotted waveguide arrays. The proposed decoupling structure consists of two columns of metal pin arrays that can suppress surface wave propagation. Also, the resu

This paper reports on the feasibility of novel low cost 3D printed antennas for millimetre wave automotive radar applications. A Fabry-Perot cavity antenna is realized using 3D metal printing technology. The performance of the manufactured antenna is

A 4.48-GHz type-II charge pump fractional- ${N}$ PLL implemented in a 0.18- $\mu \text{m}$ BiCMOS process is presented. The divider controller’s output is processed using a novel block, the probability mass redistributor, which statistically reconf
