Multiemitter BiCMOS logic circuit family

A new multiemitter BiCMOS circuit using half-micrometer BiCMOS technology with a 3.6-V supply provides 85 % improvement in delay over CMOS design and 40 % improvement over conventional BiCMOS. This benefit is demonstrated in a 64-b carry look-ahead adder where most of the gates have a high number of inputs. A complete logic circuit family based on the multiemitter (ME) concept is proposed in a gate-array structure.<
