A wide‐range (25 ns), high‐resolution (48.8 ps) clock phase shifter developed and fabricated using a 0.13 µm CMOS technology is presented. To achieve both wide range and high resolution with good linearity while minimising area and power consumption, a coarse–fine two‐step phase‐shifting structure is proposed. A delay‐locked loop with an unconventional clock input setup is used in the fine‐shifting stage to ahieve the high resolution. Test results show that the standard deviations of the differential nonlinearity and integral nonlinearity are 4.7 ps and 4.3 ps, respectively.
