Nthe circuit on the right, v1, v2, and v3 are all fixed dc voltages. m2 provides the dc current (3*ib) and m1 has a drain current with dc level ib. in normal operation, this circuit would operate with v1 providing the input signal and m3 operating as the cascode transistor with the output current flowing out of the drain. using the circuit on the right (configured to calculate the output resistance rout), find the output resistance. keep all subscripts.
