amplifying stage造句

• An astable multivibrator consists of two amplifying stages connected in a positive feedback loop by two capacitive-resistive coupling networks.
• A differential ( long-tailed, emitter-coupled ) pair amplifier consists of two amplifying stages with common ( cathode ) degeneration.
• An important consequence of this formula is that the overall noise figure of a radio receiver is primarily established by the noise figure of its first amplifying stage.
• Since the elementary amplifying stages are inverting, two stages can be connected in succession ( as a cascade ) to form the needed non-inverting amplifier.
• But testing is not confined to motorboating, can occur when an amplifying stage is too sensitive to signals fed via the power supply from a later power amplifier stage.
• It may be observed as an undesired Miller effect in common-emitter, common-source and " common-cathode " amplifying stages where effective input capacitance is increased.
• A defect in many early vacuum tube receivers was that the amplifying stages could oscillate, act as an beat notes ( heterodynes ); annoying whistles, moans, and howls in the speaker.
• Also, a voltage source should not be connected to another voltage source if their voltages differ but again this arrangement is frequently used ( e . g ., in common base and differential amplifying stages ).
• Also, a current source should not be connected to another current source if their currents differ but this arrangement is frequently used ( e . g ., in amplifying stages with dynamic load, CMOS circuits, etc .)
• In contrast with classic amplifying stages that are biased from the side of the base ( and so they are highly ?-dependent ), the differential pair is directly biased from the side of the emitters by sinking / injecting the total quiescent current.
