For the circuit provided assuming (W/L)1 = 5 design resistor R and all transistor (W/L) s such that: Iref = 25 μA, I2 = 100 μA, I3 = 15 μA, andI5 = 55 μA. Assume saturation operation with the given parameters: kn′ = kp′ = 150 μA/V2 Vtn = |Vtp| = 0.6 Vλn = λp = 0 R = kΩ (W/L)2 = (W/L)3 = (W/L)4 = (W/L)5 =
