FIELD: radio and communications engineering. ^ SUBSTANCE: proposed output stage that can be used in broadband and pulsed signal amplifying devices incorporated in multipurpose analog interface structures and voltage regulators at low supply voltages has main input 1 coupled with base of input transistor 3 whose emitter is connected on ac end to bus of power supply 4 and collector, to base of first output transistor 5; it also has second output transistor 6 whose conductivity is same as that of input transistor 3 and reverse to that of first output transistor 5; collector of second output transistor 6 is connected to emitter of first output transistor 5 and to main output 2, its emitter is connected on ac end to bus of power supply 4. Collector of first output transistor 6 is connected to bus of power supply 4 and main input 1 is coupled with base of second output transistor 6 which enhances maximal output voltage by approximately 0.7 V. ^ EFFECT: enhanced output voltage maximum. ^ 3 cl, 16 dwg |
