Abstract :
The design of a traveling wave amplifier (TWA) in a 0.13 mum standard CMOS technology is presented. It is designed to maximize the gain-bandwidth product (GBP). Asymmetric cascode, coplanar wave guide (CPW) and losses compensation technique allow to maximize the TWA GBP. Design and modeling of 90 Omega CPW used to synthesize inductors TWA´s lines is presented. Simulations with design kit and developed models for CPW show a 52 GHz bandwidth with a maximum power gain of 8.5 dB at 10 GHz for a 135 mW power consumption. Mesurement up to 40 GHz confirm this results.
