Özet:

 

In this work, we present a 200 MHz to 1.6 GHz digital   delay-locked loop (DLL) for per-pin deskew applications. The proposed phase   shifters apply linear and scalable circuit architecture for the pin-to-pin   delay mismatch of parallel I/O pins. The proposed phase detector with a   detection window and the proposed consecutive phase decision method reduce   the sensitivity to reference clock jitter. A test chip of the 0.042 mm22^{2}   DLL and the 3-ps-adjustable-resolution phase shifters with a 0.0025 mm22^{2}   per-channel area was implemented using a 90-nm CMOS process. Simulation   results show that the phase error of the 90∘∘^{\circ} phase shifter at 1.6   GHz is 2.4∘∘^{\circ}. The DLL and the phase shifter consume 3.4 mW and 0.31   mW, respectively, at 1.6 GHz.
