Abstract
A reference potential generating circuit has a current mirror amplifier (CM) supplied with an input reference potential and a feedback level, an output transistor (QP) supplied with an output of the current mirror amplifier as an input and producing an output reference potential as an output, a monitoring portion (Rand R) for generating the feedback level from the output of the output transistor, a first switch (QN) for controlling supply of a power supply potential (VSS}) to the current mirror amplifier, a second switch (QN) for controlling supply of the power supply potential (VSS) to the monitoring portion, and an output switch (TSW) for controlling connection of the output of the output transistor to a next stage. The first and the second switches and the output switch are simultaneously turned off. When a first predetermined period elapses after the first and the second switches and the output switch are turned off, the first and the second switches are turned on. When a second predetermined period elapses after the first and the second switches are turned on, the output switch is turned on.
