Class B Distortion in Audio Amplifiers

This is the famous analysis of class B amplifier cross-over distortion by the then head of HP Reasearch Labs, Dr. Barney Oliver,  published in the February 1971 edition of the HP Journal.  The ideal bias current Iq for a class B amplifier is approximated by Iq = .026/(Re+re+(rb/hFE)). This paper provies the theoretical underpinings for that relationship. So, when you hear about the ‘Oliver’ voltage, you know where it came from. You can read more about Barney Oliver here and here
