2015-09-15 Signal chain basics: Noise in ADCs
There are many different sources of noise in an ADC. Read this to learn about the three different categories based on their frequency characteristics
1999-12-14 Noise analysis of FET transimpedance amplifiers
The availability of detailed noise spectral density characteristics for the OPA111 amplifier allows an accurate noise error analysis in a variety of different circuit configurations. The fact that the spectral characteristics are guaranteed maximums that allow absolute noise errors to be truly bounded. Other FET amplifiers normally use simpler specifications of rms noise in a given bandwidth (typically 10Hz to 10kHz) and peak-to-peak noise (typically specified in the band 0.1Hz to 10Hz). These specifications do not contain enough information to allow accurate analysis of noise behavior in any but the simplest of circuit configurations. This application note discusses in detail how the OPA111 is utilized to perform noise error analysis in different circuit configurations.
