The purpose of a phase locked loop (PLL) is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned ...

Sponsored by: Texas Instruments. A phase-locked loop, of course. A PLL frequency synthesizer plays a key role in delivering the precision and accuracy demanded by many applications. The master timing ...

The phase locked loop (PLL) is an indispensible component in modern electronic systems. Its function is to generate an accurate output signal of frequency equal to, or a multiple of, the input signal ...

The phase-locked loop (PLL) has become one of the most versatile tools in the communication sector. PLLs are at the heart of circuits and devices ranging from clock recovery blocks in data ...

Fractional-N PLLs are a useful class of PLLs and not well understood. This paper explains in simple terms how these differ from a regular integer PLL. Common applications are listed along with a brief ...

Figure 1: The S-Series SGA analog signal generator offers frequency switching speeds of less than 100 µs and typical phase noise at 1 GHz of -135 dBc/Hz at a 20-kHz offset. Figure 2: Shown is a graph ...

Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have achieved a new world record in high-frequency submillimeter waves. The record-setting 324-gigahertz frequency was ...
