output voltage swing การใช้

• Cutoff clamping reduces the output voltage swing but makes the transition faster.
• That is, an active load imposes less restriction on the output voltage swing.
• This kink is the most pronounced form of "'crossover distortion "', and it becomes more evident and intrusive when the output voltage swing is reduced.
• Pentodes, therefore, can have higher current outputs and a wider output voltage swing; the anode / plate can even be at a lower voltage than the screen grid yet still amplify well.
• However, a larger feedback resistance increases the output voltage swing, and consequently a higher gain from the operational amplifier is needed, demanding an operational amplifier with a high gain-bandwidth product.
• For voltage amplification, the range of allowed output voltage swing in this amplifier is tied to voltage gain when a resistor load " R C " is employed, as in Figure 1.
• One disadvantage is that the output voltage swing ( typically ?0 20 V ) was imposed upon a high DC voltage ( 200 V or so ), requiring care in signal coupling, usually some form of wide-band DC coupling.
• The same term has been used somewhat more generally for dynamically altering the operating point of an operational amplifier ( by shifting both its positive and negative supply rail ) in order to increase its output voltage swing ( relative to the ground ).
• As a result, the current mirror does limit the allowable output voltage swing, but this limitation is much less than for a resistor, and also does not depend upon the choice of bias current, leaving more flexibility than a resistor in designing the circuit.
• If the engine runs rich ( Lambda lower than 1 ) the output voltage would be more than 0.45 V and if the engine runs lean ( Lambda higher than 1 ) the output voltage would be less than 0.45 V . The output voltage swings about 0.45 V when Lambda passes 1.
• If, for example the maximum output voltage swing of each amplifier is between a peak of + and  10 volts, when the output of one amplifier is at + 10 volts the output of the other will be at  10 volts, which means that the load ( a loudspeaker ) now sees a 20 volt peak difference between the  hot ( normally red ) output terminals.
• The long-tailed pair has many favorable attributes if used as a switch : largely immune to tube ( transistor ) variations ( of great importance when machines contained 1, 000 tubes or more ), high gain, gain stability, high input impedance, medium / low output impedance, good clipper ( with a not-too-long tail ), non-inverting ( " EDSAC contained no inverters ! " ) and large output voltage swings.
