Why does a MOSFET make a good analogue switch?
Answer: D
The channel is a genuine resistance, conducting either way with no offset voltage, and the drain and source are interchangeable - which is exactly what passing an analogue signal requires, and precisely what a bipolar transistor with its junction drop cannot offer. The threshold does drift with temperature, and the gate draws no current at all. A switch that introduces no voltage of its own is the property that matters here. Most errors on this topic come from carrying a result across from a neighbouring scheme where it does not hold.
