A cutoff frequency is tuned from 1.6 to 3.2 GHz by using two methods, namely, changing gm and switching a CMOS varactor's polarity. Output third-order intercept point reaches 13.1 dBm and total harmonic distortion

A new track-and-hold (T/H) topology improves on the existing performance limitations of the switched emitter follower (SEF) architecture. The new T/H achieves extended dynamic range, for higher input bandwidths, at lower power consumption. The FIR circuit has been included as a building block in the implementation of an analog EDC IC that is the world's first demonstration of 10.7 Gbit/s error free operation over 400 km of uncompensated SMF fiber.

Cut-off frequency is tuned by switching CMOS varactors polarity. THD is below -40 dB at 0.9 Vpp-diff output. CTF is implemented in a 0.18 mum SiGe process, it occupies 0.17 mm2 and consumes 0.3 W from 3.3 V supply.

Post-FEC error free operation is achieved with data received from over 400 km of uncompensated single mode fiber (SMF). The receiver complies with XFI Jitter specifications for Telecom (SONET OC-192 and G.709 ldquoOTU-2rdquo).
