v IN I REF V C v OUT Q 1 v O1 Q 2 Cascode for Practice 1 ECE 3150 Spring 2009 Week 10 Recitation Homework 8 due. If you have not finished the questions in Week 9 Review, do run them in details, so that they can understand the single-stage amplifier well. There is a copy of the prelim2 in 2007 on blackboard, and you should encourage students to take a look to understand the principles of using single-stage amplifiers, current mirrors and diff amp together. Additional two problems on cascode amplifiers and diff pair are provided below. If there is still time remaining, it should be used to discuss the detailed observation in Lab 3 (current mirrors) and Lab 4 (diff pair). Practice 1 (cascode amplifier): For the cascode circuit here ( Q 1 and Q 2 have identical sizing), assume an I REF = 1mA that roughly gives V GS1 = 1.5V of Q 1 (with V thn = 1V). What is the minimal value of V C that can keep Q 1 in saturation? Given a V C = 2.0V, what is the minimal value of v OUT that can keep both Q 2
