This paper presents a chare pump used in phase⁃locked loop with wide output range and low current mismatch.A negative feedback loop is employed to compensate the discharge current,which dynamically balances the charge and the discharge current and lowers the current mis...MORE This paper presents a chare pump used in phase⁃locked loop with wide output range and low current mismatch.A negative feedback loop is employed to compensate the discharge current,which dynamically balances the charge and the discharge current and lowers the current mis...
