RE: CCS Mu output question

The mu-output Z is based on delivered gm of the lower MOSFET. The drain-source voltage is based on the i*R voltage driven by the LND150 ccs. You can do this with the depletion mode FET's too in order to require a relatively large value of R-set...which de-sensitizes the circuit from minute changes in that resistor's value.
