I am trying to analyze a bridged-T attenuator circuit with the variable resistances being PIN diodes. I am trying with KCL to figure out a formula for the input voltage and current required to get a certain resistance value on the diodes from a table. Will it work to assume the diodes are ideal current sources when analyzing it this way? Or do I require both the forward current and voltage to find the appropriate input values?

Best regards,
