Source follower

Minimal monochrome circuit schematic of a single-transistor FET source follower (common-drain) stage. Show one transistor symbol with the gate on the left as the input terminal, the drain connected upward to an upper supply node or rail, and the source as the output node at the bottom or lower right. The source should feed a downward bias element such as a resistor, load, or current-source path to ground. Use thin black schematic lines, standard clean circuit-symbol geometry, and clearly labeled input and output nodes, with the source node emphasized as the output terminal.
