Magic Trifle. Bell Laboratory has a two-stage transistor amplifier, complete with resistors and condensers, that is potted in a cylinder of plastic as big as a ¾-inch section cut from a fountain pen.

2: (a) Typical 2-stage resistive feedback amplifier (b) Amplifier power vs. supply voltage However, analog and mixed-signal (AMS) circuits face a number of challenges as a result of technology scaling ...
