An 8Gb/s capacitive-coupled receiver with high common-mode rejection for un-coded data

An 8Gb/s differential receiver is demonstrated in 0.35/spl mu/m SiGe with on-chip 60fF capacitors for AC-coupling that allows uncoded data transmission for a common-mode input range of /spl plusmn/690V, with input sensitivity of 0.5 to 1.1Vpp. It especially resists to strong common-mode edges of 4V/ns for enhanced EMI rejection.
