Long tailed pair explained
WebBefore adjusting the bias of the power tubes of a Push-Pull amp (Class AB), be sure the phase splitter outputs have the same voltage swing. This video discus... WebThe Figure 3 circuit uses two npn transistors. When the input is at zero volts, Q1 is cut off, so Q2 is driven fully on via R2, and the output is low (saturated). When the input is “high,” Q1 is driven to saturation and pulls Q2 base to less than 600mV, so Q2 is cut off and the output is high (at V+). FIGURE 3.

Web9 de jun. de 2016 · The differential pair is all about balance. Thus, for optimal performance the resistors and MOSFETs must be matched. This means that the channel dimensions of both FETs must be the same and that R 1 must equal R 2. The resistance value chosen for the two resistors will be referred to as R D (for d rain resistance).
Modern differential amplifiers are usually implemented with a basic two-transistor circuit called a “long-tailed” pair or differential pair. This circuit was originally implemented using a pair of vacuum tubes. The circuit works the same way for all three-terminal devices with current gain. The bias points of “long-tail” resistor circuit are largely determined by Ohm's law and less so by active-comp… WebThe familiar ‘ differential pair ’ or long tailed pair (LTP) circuit (Figure 4.19) is not a power stage topology, but is the most important element used to control power stages, …
WebIt is fairly typical to allow about 25% to 30% HT across the tail. If your HT is fairly low (less than 200V) you may want to waste less on the tail (say 10%). Likewise if you have a very high HT you can afford to drop more across the tail. In this example the HT is 320V and we will allow 90V across the tail, leaving 230V of HT for the triodes.
