Abstract
There is provided a method for testing a switching circuit including a first FET connected between input/output terminals, a capacitor connected between one of the input/output terminals and the first FET, and a second FET that is connected in parallel with the capacitor and has a gate electrode connected to a ground terminal. The method includes, applying a potential that sets the second FET to a conducting state to the ground terminal, and testing a DC test for the first FET via the second FET.
