Acetone-sensitized irradiation using UV-B (sun lamp, lambda max = 313 nm) of deoxyfluorouridylyl-(3'-5')-thymidine monophosphate (d-FpT, F = fluorouracil), produces two major photoproducts, the cis-syn cyclobutane-type photodimer and a defluorinated (5-5) photoadduct, d-U5p5T. Product distribution is dependent on the pH of the irradiation solution, as was(More)
A supply-regulated phase-locked loop (PLL) employs a split-tuned architecture to decouple the tradeoff between supply-noise rejection performance and power consumption. The prototype PLL, incorporating a novel regulator, is fabricated in a 0.18 mum digital CMOS process and operates from 0.5 to 2.5 GHz. At 1.5 GHz, the proposed PLL achieves a worst-case(More)
