The main focus of this paper is to design a “Low power Flash ADC” for ultra-wide band applications using CMOS 90nm technology. Flash ADC consists of a reference generator, array of comparators, 1-out-of N code generator, Fat tree encoder and output D latches. The demanding issues in the design of a low power flash ADC is the design of low power latched comparator. The proposed comparator in thi...

For battery-powered electronic products, one way to extend battery life is to use a versatile step-up/step-down DC-DC converter. A new versatile step-up/step-down switched-capacitor-based converter structure is proposed, and its efficiency is analyzed. In the step-down case, the efficiency is the same as, or even better than the efficiency of linear regulators. key words: DC-DC converter, switc...

Kebutuhan energi listrik terus meningkat seiring laju pertumbuhan penduduk, kebutuhan yang sangat cepat tidak diimbangi dengan produksi energi. Saat ini nasional masih menggunakan fosil yaitu batubara, minyak maupun gas bumi. Meningkatnya penggunaan bumi tersebut berdampak terhadap menipisnya cadangan dan dapat diandalkan untuk mencukupi masa depan, sehingga perlu solusi alternatif terbarukan s...

Non-equilibrium cold plasma jets generated under atmospheric pressure by means of high voltage pulsed power generator are extended up to a few centimeters long in the surrounding air. The generator is consisting of a negative dc source, a Blumlein-type pulse-forming network (E-PFN), and a dynamic spark gap switch. The plasma jet generated by the device using helium as the operating gas depends ...
