Abstract :
A 130mA 2.5V 7-tap analog FIR equalizer for 10Gb/s fiber-optic links is implemented in a 0.12 μm CMOS process. The filter precedes the receiver CDR and recovers data signals distorted by multi-mode fiber dispersion over a 600m link to a BER <10-12. Tap delays are implemented by a combination of passive and buffered LC transmission lines.
