Why I Design Current Feedback Amplifiers
A considerable amount has been written about voltage feedback amplifiers (VFA) over the years, but comparatively little attention has been paid to current feedback (CFA) types. Both Robert Cordell and Douglas Self focus almost exclusively on VFAs, with little to no in-depth analysis or consideration of CFAs as viable alternatives to the prevailing VFA-dominated linear…

The Endless Semantic Debate: Current and Voltage Feedback Amplifiers
It seems some are still agonizing over the ‘current feedback’ versus ‘voltage feedback’ definition. Clearly a case of people wanting to continue to flog a horse that was laid to rest five decades ago during the heyday of the analog computer, or they simply fail to grasp the CFA concept. I suspect there are an…

Ovation e-Amp: A 180 Watt Class AB VFA Featuring Ultra Low Distortion
The e-Amp is a 180 Watt RMS (very conservatively rated into 8 Ω ) fully balanced symmetrical (‘FBS’) amplifier featuring an emitter follower triple (EFT) bipolar output stage and beta enhanced VAS stage. The amplifier can be configured using jumpers for TMC (Transitional Miller Compensation) or straight Miller compensation (MC). The VAS can be lightly…
