As you might have discovered, the secret to Blue Tiger Analog's prosperity is to slightly modify off-the-shelf components for new applications. Your boss again restocks many inverters during a discount wholesale, and he wants you to make expensive amplifiers out of those cheap inverters. "Just solder a resistor and we can make a good fortune!", he said. VDD = 5V Iin W₂ - Wp 3, Ln Lp Vin (+ ww Ip - Vout IN Figure 5: Amplifier out of an inverter. Use the following parameters to solve the following question = = 6, µnCox = 50µA/V², µpCox = 25µA/V², VTn = 1 V, VTp| = 1 V, An = p = 0. a Write the equation relating Iin (The current flow out of Vin), In, DC, and Ip,DC. b Sketch Vin versus Vout from 0 to VDD. What is the value of Vin (let's call it Vin1) when NMOS just turn on? What is the value of Vin (let's call it Vin2) when PMOS just turn on? c If the input DC bias voltage is 2.5 V, what is the expected output DC voltage? What regions are the transistors operating in?
d For both Vin=0 and Vin=VDD, calculate In, Ip and Vout. e Why inverters (without the resistor) cannot make a good amplifier? f Bonus point: what is the expression of the gain of the amplifier?
