2. Current Mirror: Consider the circuit shown below. Assume that both of the transistors are matched, meaning: 1) K„' is the same for both devices M1 and M2, and is equal to 1mA/V?; 2) Vr = 0.5V for both M1 and M2. Recall that K= K,' (W/L), where W is the width and L is the length of the MOSFET. Further assume that VD. 3V and Vo is large enough that M2 operates in the saturation regime. VDDO Vo IREF M1 w, H M2 W2 L2 In what mode does M1 operate and why? b. Find the relationship between I, and IREF in terms of the MOSFET parameters. c. Find VGs if IREF= 10mA, W,= 10µm, and L, = 1µm. d. Find Io under the conditions in part (c) if W2= 20µm and L,= 1µm. What is the minimum value for Vo to ensure M2 is in saturation under the conditions of part (d)? а. е.
