0.1-Hz to 10-Hz amplifier noise measurement filter reference design
Texas Instruments
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.See more TI Precision Designs
