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.
