FIELD: radio engineering and communications, possible use as device for amplifying impulse signals in structure of analog interfaces of varying functional purpose. ^ SUBSTANCE: operational amplifier (dwg.2) contains input cascade (1) with expanded range of active operation, having first output (2), synchronized with bus of positive power source (4), second output (5), synchronized with bus of negative power source (6), two-clock output cascade (7), having first input (8), synchronized with bus of positive power source (4), second input (9), synchronized with bus of negative power supply (6). First output (2) of input cascade (1) is connected to collector output of first additional current mirror (10), emitter output of which is connected to first input (8) of two-clock output cascade (7), second output (5) of input cascade (1) is connected to collector output of second additional current mirror (11), emitter output of which is connected to second input (9) of two-clock output cascade (7), while input (12) of first current mirror (10) is connected to first support current supply (13), and input (14) of second current mirror (11) is connected to second support current supply (15). ^ EFFECT: increased reliability of operation with preserved maximal possible speed of operation for linear operation modes. ^ 2 cl, 9 dwg |
