摘要

This paper presents a fast-corrected all-digital duty-cycle corrector (DCC) with synchronous input clock. The proposed DCC has many features, including fast locking in 4 cycles, wide range correction, and synchronous 50% duty-cycle clock with an input clock. The circuit can operate from 500 to 900 MHz and corrects a wide range of input duty cycle ranging from 25 to 75%. The duty-cycle error of the output clock is between -2.4 and 2.7%. The largest static phase error between the input and output clock is -44 ps at 900 MHz. The RMS and peak-to-peak jitters are 1.9 and 14.7 ps at 900 MHz, respectively. The proposed DCC is implemented in a 0.18-μm complementary metal oxide semiconductor process. The proposed DCC occupies an area of 0.05 mm2 and dissipates 23 mW with 1.8-V supply voltage at 900 MHz.
