-- 2 -- 2 BALANCED OUTPUT RAIL-TO-RAIL SECOND GENERATION CURRENT CONVEYOR AND FULLY BALANCED DIFFERENTIAL RAIL-TO-RAIL SECOND GENERATION CURRENT CONVEYOR HAVING THE SAME

摘要

The present invention relates to a balanced output rail-to-rail second generation current conveyor and a completed balanced differential rail-to-rail second generation current conveyor including the same. The balanced output rail-to-rail second generation current conveyor comprises a core block and a driving block. The core block implements rail-to-rail input/output through an upper differential input end and a lower differential input end which are commonly connected to a Y-port and an X-port. The core block outputs first driving voltage (P_DRV) and second driving voltage (N_DRV) by mirroring current applied by a bias voltage based on a voltage of the Y-port and a voltage of the X-port. The driving block outputs normal output current through a ZP-port in response to the first driving voltage (P_DRV) and the second driving voltage (N_DRV), and outputs reverse output current with a reverse phase for the normal output current through a ZN-port.
