Abstract :
In order to increase the frequency locking range, a delay-locked loop (DLL) circuit with frequency to voltage converter (FVC) and phase select circuit is described. For the low power dissipation consideration, the circuit´s bias current is keep at lower level. The simulation results show that the operating frequency range extend from 106 MHz ~ 151 MHz to 54 MHz ~ 250 MHz, and the power dissipation increases from 2.47 mW ~ 3.33 mW to 6.7 mW ~ 14 mW.
