"WebCurrent gain is normally taken off the emitter (of a transistor )and implies there is no voltage gain, but the drive impedance is lowered, possibly a great deal. This is sometimes called a 'Buffer', because it isolated the previous stage from the next stage, which could be a speaker, if the circuit was an amplifier.

Web27 de ago. de 2024 · Phosphate absorption occurs in the gastrointestinal tract through paracellular absorption and transcellular transport. The paracellular pathway does not saturate and has a significantly higher absorption capacity than does the transcellular pathway. Evidence indicates that this pathway is the primar … In analog circuits a high impedance node is one that does not have any low impedance paths to any other nodes in the frequency range being considered. Since the terms low and high depend on context to some extent, it is possible in principle for some high impedance nodes to be described as low impedance in one context, and high impedance in another; so the node (perhaps a signal source or amplifier input) has relatively low currents for the voltages involved.
