THIS WIDE VOLTAGE FLUCTUATION CMOS OUTPUT STAGE, PARTICULARLY SUITABLE FOR OUTPUT BUFFERS IN ANALOGUE MONOLITHIC SUBSYSTEMS, IS EXPOSED. THE OUTPUT STAGE, INCLUDING TWO COMPLEMENTARY MOS TRANSISTORS M18, M19 MOUNTED IN PUSH-PULL, AND A FEEDBACK 1, 2 TO IMPROVE FLUCTUATION AND LINEARITY CHARACTERISTICS COMPARED TO THOSE OF THE OUTPUT STAGES WITHOUT FEEDBACK FROM THE TECHNOLOGY PREVIOUSLY, SUFFICIENT STABILITY CHARACTERISTICS BEING REBUILT BY LOCAL COMPENSATION. IN ADDITION, THE IDLE CURRENT IS STABILIZED BY A SPECIAL CONTROL CIRCUIT WHICH COOPERATES WITH THE LOCAL FEEDBACK CIRCUIT. |
