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 ...

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 ...

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) ...
