I want to use low voltage capacitors in high voltage circuits to save on cost which would require floating ground to x volts below the supply but I also need this new "ground" to be super low impedance to earth so the circuit can draw its AC current through it and nothing else.
I can't think of a way to do this, anything I can think of requires a high value resistor and any resistor will screw up the impedance. Zeners won't work.
Source followers won't work. I thought maybe a push pull current source could work but it refuses to boot up in LTspice so I don't know if that will work or not.
Can this be done?
