What would you call it?

Add another wire and call it an Ideal bias tee.

Good idea for a separate part. ...Jim Thompson

Here you go...

• I've developed a simple-minded subcircuit for use with current NOISE
• analyses in Spice/PSpice/LTspice such that...

• It passes DC at whatever RDC you set

• It jumps to gmin/2 at some corner you set, FCO

• It's a flat impedance at gmin for the rest of the spectrum

My symbol...

'Flat Gain brick wall Filter with DC'?

If I read that right.

You designed it ?

Thompsostat one.

That would work, but I settled on "AC-BLOCK" ;-)

Some may wonder, "What the hell", but this is a just a convenience for doing both input-referred voltage and current noise analysis in a single simulation run, as one often goes up as the other goes down... making it more easy to visually optimize an amplifier input structure.

{Parameter "ACTIVE" allows me to turn it on and off as appropriate during the STEP PARAMETER routines.) ...Jim Thompson
