the values on my figure aren't correct
the gate of M7, M9 is floating
it was just the values from previous simulations.
it is not about rout .
it is about a phase shift. i need m7, m9 to act as resistance of average value 1Mohm. (in sat i think we can't get this value from a single transistor)
i need a sharp phase shift that the phase =180 for 40MHz and zer0 phase for 120MHz , this can be achieved with the help of caps (but i need Resistance (large values actually))
it may never work in sat because it is connected to the gate of other mosfet that the DC volts should be equal on drain and source of M7, M9. (vds alomst zero)
i just bothered of how to connect the gates(M7,M9) to ensure a subthreshold working , i think i need other mosfets (diode connected for example to reach the goal ) but i dont know how to connect them together
thnx for ur help
