Abstract

A novel phase locked loop design utilizing novel phase-frequency detector, charge pump, loop filter and voltage controlled oscillator is disclosed. The phase-frequency detector includes a dual reset D-flip flop for use in multi-GHz phase locked loops. Traditional dead zone issues associated with phase frequency detector are improved/addressed by use with a charge transfer-based PLL charge pump.
