For the circuit below, perform the following calculations: (i) Find I1 when VIN = 1.2 V and R1 = 2 kohm. (ii) If W/L of the transistor is changed to W/L = 80/1, compute the new value of overdrive voltage VOV such the current I1 remains the same as in part (i). (iii) Find the maximum value of R1 which ensures that the transistor remains in saturation. (iv) Determine the minimum value of supply voltage VDD to bias the transistor in saturation.
You'll get a detailed, step-by-step and expert verified solution.
