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 ...

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 ...

Many noise sources can plague high-speed radio-frequency (RF) analog signal chains, making design considerations that much more challenging. Both megahertz and sub-terahertz sampling-rate converters ...

Generally speaking, noise is any electrical phenomenon that is unwelcomed in an electrical system. This article is the first of a three-part series about noise in the signal chain. Here we focus on ...
