Let VDD = 5V and IB = 1mA. Set up the circuit in LTSpice. Calculate the required value of the resistance at the drain of M6. Use the ALD1101 and ALD1102 transistors. For the LTSpice simulation to be accurate, it will be necessary to use the correct SPICE models for the transistors. 1. Run a DC sweep simulation, sweeping the DC input common mode voltage at the input terminals, Vip and Vin. Find the DC bias voltage at which the current through each branch of the differential pair is equal to half of IB. 2. Now, set the DC common mode voltage at the terminals to the bias voltage found in part 1. Apply a small sine wave at Vip, keeping the DC offset voltage at both terminals. A 10mV amplitude at 1kHz sine wave would be appropriate. Report the differential gain of the amplifier. 3. Apply a small sine wave to both input terminals to find the common mode gain. 4. Calculate the Common-Mode Rejection Ratio (CMRR) of the amplifier
