A MOS current mirror is shown below. For matched transistors Q₁ and Q2, with W/L = 20, μnСox = 300 µA/V², and Vtn = 0.4 V, design a current mirror to provide a current output - 10 160 μA with VDD = 2.0 V. Neglect the effect of channel-length modulation. Find: a) The value required for R in the current IREF b) The minimum value that V can have while Q2 still operates in saturation.
