Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The chapter details the design and implementation of a 2 GHz wide tuning range LC-tank digitally controlled oscillator (DCO) in 28 nm CMOS technology. The DCO is designed to operate between 1.25 GHz and 2.5 GHz with a frequency resolution of 10 MHz, enabling dynamic control of processor clock frequency and supply voltage. Key features include the use of digitally controlled capacitor banks for frequency tuning, a symmetrical CMOS LC-tank structure for improved loop gain and phase noise, and a current sink design to ensure stable oscillation across a wide frequency range. Post-layout simulations confirm the DCO's ability to cover the specified frequency range with high resolution and low phase noise, making it a competitive solution in the field of digitally controlled oscillators.
