摘要

A plurality of source-grounded transistors (3) are connected in parallel to each other, and a plurality of gate-grounded transistors (4) are connected in parallel to each other. Sources (4s) of the gate-grounded transistors (4) are connected to drains (3d) of the source-grounded transistors (3), respectively. A plurality of ground pads (5) are connected to sources (3s) of the source-grounded transistors (3). A plurality of grounded capacitors (6) are connected to between the ground pads (5) and gates (4g) of the gate-grounded transistors (4). Between the ground pads (5) and the gate-grounded transistors (4), the source-grounded transistors (3) and the grounded capacitors (6) are alternately disposed.
