Hi Kura,

See the data below. Note that the circuit I used did not have the Ruv2 and Rhyst included, but you can easily account for the leakage through the Ruv resistor network. Estimate is also provided including the leakage through the Ruv resistor network.

Thank you for your reply.

I'd like to confirm that you got data at follow condition.

Ruv2 open and Rhyst open ?

Kura-san,

That is correct. Ruv2 and Rhys were open.
