Abstract
A frequency multiplier includes a first digitally controlled delay line (DCDL) configured to receive a first clock signal and generate a second clock signal by changing a phase of the first clock signal, a multiplying delay-locked loop (MDLL) configured to generate a third clock signal by multiplying a frequency of the second clock signal, and a DCDL calibration circuit configured to receive the second clock signal and generate a gain signal for adjusting a gain of the first DCDL where a difference between a maximum delay and a minimum delay of the first DCDL is substantially equal to a period of the third clock signal.
