Abstract :
A high-speed phase rotator (PR) using simple resistive interpolation is proposed for high-speed serial I/O. It operates from 1.875 to 3.45GHz and generates eight phases, spread over a full 360°, which are divided into 136 equal parts to give a resolution of 2.65°. To demonstrate the effectiveness of the proposed PR, a prototype half-rate 3.75°6.9Gbit/s serial-link receiver is designed and fabricated.
