ABSTRACT:
A switching point detection circuit for detecting a switching point according to a fabrication condition of a MOS transistor includes a reference voltage generation circuit for generating a reference voltage, a first CMOS inverter circuit for receiving the reference voltage, and a second CMOS inverter circuit for receiving the reference voltage, wherein an NMOS transistor is a dominant transistor for the reference voltage in the first CMOS inverter circuit and a PMOS transistor is a dominant transistor for the reference voltage in the second CMOS inverter circuit.
