A two transistor current-controlled current conveyor (C4) circuit is provided which exploits the translinear properties of the MOS transistor in subthreshold and uses unidirectional current signals. As a result, the circuits of the invention achieve high functionality and integration density with very...http://www.google.com/patents/US5206541?utm_source=gb-gplus-sharePatent US5206541 - Current-mode based analog circuits for synthetic neural systems
