While troubleshooting the power supply of a 1970s Centurion system, [Usagi Electrics] came across a fascinating feature of these units: the ferroresonant, or constant voltage transformer (CVT). The… ...

Look in to rail-to-rail (RRIO) op amps designed for running from 5V supplies. Plenty of modern op amps are made for operating with +5V and Gnd because that’s what they’ll be given in modern ...

Splitting a rail using the voltage reference will often mean compromising a bit on the symmetry of the split, for example, if a 3V3 rail is to be split then the closest would be to use the 1.8V output ...

Dual Split-Rail Supplies. This approach can be used when bipolar supplies are required from a single supply input, provided the load currents are modest. The power dissipation in all dc/dc converter ...
