Transconductance amplifier

Rectangular transconductance amplifier block in clean textbook schematic style, shown as a two-port voltage-controlled current-output element. The left side has a differential voltage input terminal pair marked plus and minus, with short lead lines extending outward. The right side has output terminal(s) with a clear current indication, typically an arrow showing current delivered at the output. The block is labeled Gm or g_m, with crisp black engineering outlines on white; may optionally include input/output resistance labels or a small internal dependent current-source symbol to indicate current proportional to input voltage.
