Abstract
A clock generator based on a phase-locked loop with one pole and an improved period jitter characteristic is disclosed. The clock generator comprises a phase detector for generating a phase detection signal and a phase error signal, a charge pump for generating a loop control voltage, a loop filter for generating an integrated voltage signal, a voltage-controlled oscillator for generating multi-phase output signals, and a phase error compensating circuit for compensating a phase error generated at a prior input clock. The clock generator has an improved period jitter characteristic by compensating a phase error generated at a prior input clock.
