Abstract
A semiconductor device having a large bias component detects a faint signal component on the bias component, includes a first bias circuit with a reference resistance connected to a measuring resistance group and having the same resistance temperature coefficient as the measuring resistance, a second bias circuit provided with a reference resistance being connected to a cancel resistance and having the same resistance temperature coefficient as the cancel resistance, and a third bias circuit provided with a reference resistance being connected to a correction resistance and having the same resistance temperature coefficient as the correction resistance. The first bias circuit is for applying the output voltage to the measuring resistance group; the second bias circuit is for applying the output voltage to the cancel resistance; and the third bias circuit is for applying the output voltage to the correction resistance.
