Abstract
A VDSL receiver front-end with a programmable
gain low noise amplifier is presented. The amplifier
consumes only 35mW from a 3.3V supply in a
0.35μm BiCMOS technology and is suitable for
DMT-based VDSL systems with bandwidths up to
12MHz. The linearity is expressed in Missing Band
Depth (MBD) for a worst case bandplan . The LNA
uses an inverting architecture and has a constant
input impedance. A technique was used to suppress
the distortion caused by the switches in the signal
path. The area is only 0.2mm2.
