Direct coupled circuits
WebJun 20, 2024 · If you spend enough time haunting DIY tube amp websites and books, you will inevitably come across the theme of direct-coupled tube circuits. N-type and p-type transistor sandwiches make direct coupled circuits almost trivial. Tubes, which are "n-type" only, are not quite so simple to marry anode to grid. And yet the siren sings, … WebFigure 7. Using an op amp to provide a "phantom ground" for battery-powered direct-coupled applications. Circuit Turn-On Time Issues. One final issue that needs to be considered is circuit turn-on time. The approximate turn on time will depend on the RC time constant of the lowest-bandwidth filter being used.

WebIn analog circuits, a coupling capacitor is used to connect two circuits such that only the AC signal from the first circuit can pass through to the next while DC is blocked. This technique helps to isolate the DC bias settings of the two coupled circuits. Capacitive coupling is also known as AC coupling and the capacitor used for the purpose ...

A direct-coupled amplifier or DC amplifier is a type of amplifier in which the output of one stage of the amplifier is coupled to the input of the next stage in such a way as to permit signals with zero frequency, also referred to as direct current, to pass from input to output. This is an application of the more general direct coupling. It was invented by Harold J Paz and Francis P. Keiper Jr. in 1955. It displaced the triode vacuum tube amplifier designed by Lee de Forest.
