Part 6 of this 12-part Resolving the Signal series focuses on output- versus input-referred noise, adding an amplifier at the input of an ADC, and low- versus high-resolution ADCs as they relate to amplifier noise.

The Blomley amplifier was designed over forty years ago, is an alternative power amplifier design that suffers virtually no distortion, and provides a sound which has the presence often lacking in conventional amplifiers.

High precision op amps enable system designers to create circuits that condition signals (amplify, filter, and buffer) while maintaining the precision of the original signal. The precision of the total system depends on maintaining the precision of the signal path.
