Each regulator is matched to the subsequent operational section by applying the most appropriate type of regulation circuit (series
regulation, shunt regulation, optimised for lowest noise, optimised for lowest impedance etc.) The result is that every power supply
section is fully optimised for every digital circuit to ensure the best possible performance.
The end product was certainly worthwhile, as supply noise has been reduced by a factor of more than 1000 times compared to standard
regulators to result in the virtual elimination of digital noise.
