Abstract :
Linear weighted addition is one of the basic operations in linear systems. A simple scheme for the weighted addition of voltage signals in CMOS technology is described here. The scheme is characterized by high bandwidth, high linearity, accurate gain and gain bandwidth products close to 1 GHz in 0.5 μm CMOS technology. Experimental results are shown that verify functionality of the proposed approach
