Common source mosfet amplifier

Clean black textbook schematic of a single-stage common-source NMOS amplifier, centered on an n-channel MOSFET with gate on the left, drain at the top, and source at the bottom. The drain connects upward to a resistor load, and the output is taken from the drain as a labeled node. The gate is driven from the left through an input coupling capacitor and includes a gate-bias resistor. The source connects downward toward the lower reference node/ground through a current-source branch, with a bypass capacitor to ground. Use standard circuit-symbol proportions and a simple, centered textbook layout with labeled input and output connection points.
