Line interface circuit, associated line drivers and methods of operating the same |
摘要 |
A line driver is disclosed comprising a termination portion which includes a termination resistance (Rterm) and which is supplied in use by an operational amplifier (op-amp), with a termination current (VNE/R) for load matching. The termination portion further comprises a back-termination transformer (1:alpha) which is series coupled with the termination resistance (Rterm). The power dissipated in the termination resistance (Rterm) is less than the power (P/2) available to a signal transmission portion for signal transmission along an associated transmission line (Rload) and the power consumption efficiency of the line driver is improved.
