Op Amps - The Norton CDA

Posted by jc2048 Aug 30, 2018
Introduction   This blog is a bit off the beaten track and features an unusual form of op amp called a Norton amplifier. Perhaps I should have called it 'Op Amp Inessentials'! If it's not your kind of thing, skip it and go on to something more interesting.   The devices have been around for a long time but I've never had any cause to use one in a design. People are obviously still using them, though, as TI (who now own National Semiconductor) still list and sell the device I'm go ...
Introduction   Even more oscillators!   At some point, for reasons I can't remember now, I tried simulating some simple sine wave oscillators. At the time they all got left in the simulator's default save directory which is where I've been retrieving them from.   The last blog looked at a very simple and, to be honest, not very good single-transistor design Transistors: Phase-Shift Sine Wave Oscillator   This one, in contrast, uses op-amps to provide the gain and p ...
