Design a CMOS Differential pair amplifier with a low frequency gain of at least 30dB, while driving a resistive load 50 ohm. The available circuit components are NMOS transistor, PMOS transistor, resistors, capacitors and inductors. Ideal sources can only be used to generate the supply voltage VDD & GND. All the biasing circuitry (voltage divider, current mirror...etc) has to be generated from the supply voltage.
