ABSTRACT:
A dual-source F.E.T. connected in a common gate arrangement for receiving respective input signals at the two-sources and for producing at a drain terminal the sum of the input signals. A circuit is disclosed which combines the dual-source F.E.T. with a single-source F.E.T. for mixing the input signals.
