More Notes On Cascode Amplifier Oscillation

Here is a short write up on cascode oscillation I did back in 2012 when designing and developing the e-Amp. Cascode Oscillation in Audio Amplifiers.pdf I recently (2017) had a recurrence of the problem on another high power design – some pictures are shown below.  When I went back and looked at the notes above, […]

Output Coupling Inductors

Inductors on the output of an amplifer are used to isolate the amplifer from capacitive loads at HF and ensure stability.  There has been quite some debate on DIYaudio.com as to whether they are audible, necessary, or just the result of designers being overly cautious.  Some very well known designers in the field have decided against using […]
