Design the circuit (specify R Q and R L ) to achieve the maximum possible voltage gain while achieving an output swing of at least 1V (zero-to-peak) and a bandwidth of 1GHz. The supply voltage V CC = 3V and the load is a C L = 200fF capacitor. Assume the amplifier is driven by an ideal voltage source. (a) If an input voltage is applied at v i , it consists of both differential and common-mode components. Calculate the voltage gain for a common mode signal and the common-mode rejection ratio ( CMRR ). (b) Derive the large signal input/output relationship for low-frequency signals. For simplicity, assume the input signal is truly differential. Plot the input/outputsimplicity, assume the input signal is truly differential....
