0.1-Hz to 10-Hz amplifier noise measurement filter reference design
TIPD122
Overview
This circuit is designed to amplify low frequency noise (0.1Hz to 10Hz) to a level that is easily measured by and oscilloscope. It achieves this function with a 0.1Hz second order high pass filter and a to 10Hz forth order low pass filter. The 0.1Hz to 10Hz noise measurement is a common figure of merit given in amplifier data sheets. This design is intended to facilitate the measurement 0.1Hz to 10Hz noise for the commonly used different package styles.
Features
- Filters 0.1-Hz to 10-Hz noise
- Amplifies noise by a factor of 100,000 x
- Allows for testing of common amplifier package configurations
This verified design includes:
- Theory
- Component Selection
