Abstract

In this paper, we propose a delay-locked loop (DLL) with a closed-loop duty-cycle correction (DCC) circuit. The proposed DCC circuit does not require additional blocks for DCC, and this enables it to have a significantly reduced power consumption and area. To increase DCC accuracy, we also propose a duty cycle keeping fine delay line. The proposed DLL is implemented using a 0.13 μm process with a supply voltage of 1.2 V. The active chip area is 0.02 mm2. The operating frequency range of the proposed DLL is from 400 MHz to 800 MHz. At all operating frequencies, the proposed DLL achieves an output duty-cycle error between -0.8% and 1.04% for an input duty cycle from 30% to 70% and the power consumption of the proposed DLL is 3.84 mW.
