J. Lee et Ap. Freundorfer, MMIC adaptive transversal filtering using Gilbert cells and is suitable for high-speed lightwave systems, IEEE PHOTON, 12(2), 2000, pp. 196-198
An adaptive transversal tilter (equalizer), which has positive and negative
tap weights, will be discussed, Measured results will be presented that sh
ow an increased passband control. An example of pulse shaping/generation of
a modified duobinary signal is also shown.
