Abstract. Circuit schematic of a ring pulse oscillator for synchronization and information converting devices on the base of local phase interpolation elements is developed. The leading interpolation principle combined with electronic regulation of interpolation axis provides a wideband frequency tuning at a reduced time sampling increment. Results of study an integrated oscillator built with 50-nm technology is examined in modeling environment LTSpice4.
Keywords: ring oscillator, pulse repetition rate, delay time, delay element, phase interpolation, modulation characteristic
