2. Since the input impedance of each subsequent stage of a cascaded amplifier forms the load of the previous stage, the design should start with the last stage and proceed backwards to the input. Therefore, begin your design with the CC output stage. The first design step is to select an appropriate bias current based on the stated swing requirement. This enables you to find the numerical values for the input and output resistance, respectively and thus the voltage gain under the given operating conditions. To find values for the biasing circuitry, derive symbolic expressions for input resistance, output resistance and voltage gain and then compute the resulting numerical values.
