Cmos common source amplifier

Black line-art CMOS common-source amplifier schematic using standard MOSFET symbols with gate, drain, and source terminals clearly shown. An NMOS transistor at the bottom serves as the amplifying common-source device, with its gate as the input. Above it, PMOS transistor(s) form the active-load/current-mirror arrangement at the top of the circuit. The transistors are arranged in a compact vertical stack between supply and ground, with the output taken at the shared drain node. Label the devices Q1, Q2, and Q3 near the corresponding transistors, using thin schematic lines and a clean balanced layout.
