Abstract
Increased bandwidth per pin is necessary to support the growing data throughput in mobile systems. This article presents a low-power simultaneous bidirectional (SBD) trans- ceiver employing a novel voltage-mode driver with a resistor- transconductance (R-gm) hybrid subtractor to enable concurrent transmission and reception of data on a single differential channel. A finite impulse response (FIR) filter-based adaptive echo cancellation system that cancels both near- and far-end echoes allows for th
