ABSTRACT:
The disclosed substrate potential detecting circuit can reduce both the power consumption and the pattern area thereof. The substrate potential detecting circuit comprises: a series circuit composed of a plurality of same-conductivity type MOS transistors. Each transistor has a source terminal connected to a substrate terminal thereof and a drain terminal connected to a gate terminal thereof. Further, the channel widths of all the MOS transistors are determined equal to each other and so selected that all the transistors can be operative in a sub-threshold region, respectively.
