Ferroelectric Capacitor based Adaptive Differential Equalizer

Abstract

In this paper, a novel architecture of passive adaptive differential equalizer is reported. The proposed architecture has a fixed PCB layout, yet it provides bandwidth control of the frequency response using a ferroelectric tunable capacitor. The equalizer circuit occupies an area of 5 mm2 and demonstrates a wide tuning range of 1 GHz for a DC bias range of 1-10V.
