Question: consider the circuit shown below assume that both of...

Question details

. Consider the circuit shown below. Assume that both of the transistors are matched, meaning: 1) K,, is the same for both devices Mi and M2, and is equal to 1 mA/V, 2) Vr= 0.5V for both MI and M2. Recall that K= K,, (WL), where W is the width and L is the length of the MOSFET. Further assume that Voo - 3V and Vo is large enough that M2 operates in the saturation regime. VDD lo IREF M1 W. L1 M2 L2 a. In what mode does M1 operate and why? b. Find the relationship between lo and IRef in terms of the MOSFET parameters c. Find VOs if!REF-10mA, Wi-10μm , and Li-lụun. d. Find lo under the conditions in part (c) if W-20 μm and L,-1 μm. e. What is the minimum value for Vo to ensure M2 is in saturation under the conditions of part (d)?
