This paper presents a 10 Gb/s receiver that consists of an equalizer, an inter-symbol interference (ISI) monitor, and a clock and data recovery (CDR) unit. The Cherry-Hooper topology was employed to realize an adjustable high-bandwidth equalizer with reduced area and power consumption, without using on-chip inductors. The ISI monitor measures the post-cursor and pre-cursor ISI in the equalizer output. The ISI measurement is achieved using a switched-capacitor correlator. A test chip was fabricated in 0.11 μm CMOS. The areas and power consumptions are 47 μm×85 μm and 13.2 mW for the equalizer and 145 μm×80 μm and 10 mW for the ISI monitor.
