A low-voltage fully differential, voltage-controlled transconductor is described. The proposed transconductor achieves a wide input/control voltage range, with a highly linear transconductance factor and truly fully differential output currents. The transconductor is used to implement a G(m)-C adaptive forward equalizer (FE) for a 125 Mbps wire line transceiver using digital core transistors with channel length of no more than double the feature size in a typical digital CMOS 180-nm process and supply voltage as low as 1.6 V. The adaptive FE enables IEEE 1394b transceivers to operate over UTP-5 cables for up to 100 m in length. The transconductor stage occupies 1945 mu m(2) and consumes an average power of 418 mu w at 125 Mbps and 1.8-V supply.
