  • A low-jitter and low-power dissipation delay-locked loop (DLL) is presented. A proposed multi-band voltage control delay unit (MVCDU) is employed to extend the operation frequency of the DLL by controlling the delay cell within the MVCDU. The jitter of DLL is reduced due to MVCDU's low sensitivity. The delay cell in the MVCDU employs a differential configuration to further reduce the noise impact from the fluctuation in the supply and ground voltage. The operating frequency of the proposed DLL… CONTINUE READING
