A 3.3-V ISDN U-interface line driver with a new IQ-control circuit.

A 3.3-V ISDN U-interface line driver with a new IQ-control circuit.

In this work, we propose a new quiescent current (IQ) control circuit applicable to line drivers for digital subscriber line (DSL) applications. The line driver consists of preamplifier, error amplifiers, output transistors, and IQ control circuits. A new method is proposed for controlling IQ values...
