nature of the device. So I will state here and now that I consider “no feedback” to be where feedback does not extend further than a single gain device or stage, so that circuits having “local feedback” are still considered “no feedback”. Anybody disagreeing with this should send me a diagram of a “true no feedback” circuit, and I will try to point out the hidden feedback
sink in it. Now I strive to be like Picasso, who could draw a woman with a single pencil stroke and create a masterpiece
feedback with a Supersymmetric connection another 20 dB or so. This is easily accomplished with only one gain stage instead of the multiple stages required by conventional design, and so it results in only one “pole” of high frequency characteristic, and is unconditionally stable without compensation. In fact, if you build a supersymmetric circuit with multiple gain stages, it does not work as well
d the differential distortion with supersymmetry
On this curve B we can clearly see that intrinsic symmetry due to the matching of the two halves reduces the distortion by a factor of 10. Supersymmetry D creates a more perfect match, and results in an additional reduction by a factor of 10. However there is essentially no difference in the distortion figures at the output C of each half of the circuit considered alone. Supersymmetry does not work by reducing the distortion per se, rather it works to precisely match the two halves of the circuit and lets the balanced output ignore the unwanted components. As long as the two halves are matched, this performance tends to be frequency independent, and does not deteriorate over the audio band. With mid-leveldistortion figures on the order of .002%, this is very high performance for a single balanced gain stage
