摘要
This brief presents a data-pattern-tolerant adaptive equalizer using the spectrum balancing method. In addition to a high-frequency boost control loop, this equalizer has a corner frequency control loop to guarantee its accurate adaptation for various data patterns and data rates. Measured results show that the jitter of the eye is reduced by a maximum of 37% when compared to the previous spectrum balancing equalizer. The chip is fabricated in a 0.18-mu m CMOS process, and the equalizer core occupies 0.35 mm(2) and consumes 85 mW.
