A design idea for a white-noise generator is realized and revised. Two low-noise amplifiers (LNAs) in cascade amplify the noise produced by a reverse-biased Zener diode operating in junction-breakdown ...

Why You Can’t Just Use a Spectrum Analyzer Industry has an increasing demand for spectrally pure signals in applications such as imaging radar, mobile communications, satellite communications, weather ...

Separating the power/ground connections used for the analog sections from those used for the digital areas will improve the isolation of the power supplies. Adding external/internal filtering should ...

Digital transition switching is the primary cause of noise in mixed-signal devices. Signal noise and immunity to power, ground, and substrate noise all benefit from using differential circuits. Design ...
