The almost universal choice in semiconductor power amplifiers is for a unity gain output stage, and specifically a voltage follower. Output stages with gain are not unknown, 1 but they are not common.

Distortion comes in two basic classes: Linear distortion, which is not an oxymoron; and nonlinear distortion, which includes all other distortions except noise. Noise is quite another matter and is ...

Transmitting high-speed data over a cable or printed-circuit-board (PCB) path will significantly attenuate and distort the signal. Transmission paths are usually transmission lines that introduce ...

High-speed analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) typically are characterized using continuous wave (CW) signals. There are several reasons for this practice: 1) ...

Achieving unidirectional signal flow—where information travels in only one direction—is vital for next-generation communication systems. Micromechanical devices leveraging parity-time (PT) symmetry ...
