Abstract
In the present semiconductor integrated circuit device, a buffer is provided between a constant-current source circuit and an internal circuit that becomes a source of noise. The buffer controls the potential of an output node such that the potential of the output node becomes the bias potential. Even when noise is generated on the bias potential line when the internal circuit is in operation, the buffer dampens the noise. Thus, the noise generated in the internal circuit is prevented from adversely affecting the constant-current source circuit, and a stable operation of the internal circuit itself is achieved.
