Abstract :
A layout-based optimal neutralization technique is proposed for the designs of mm-wave differential amplifiers. Based on a new layout style which exploits routing signal capacitive coupling, the need for physical neutralization capacitors are obviated which results in compact and robust layout. Experimental prototype designs at 60 GHz and 110 GHz amplifiers demonstrate the utility of the idea by direct comparison with unneutralized designs.
