Abstract
A bandgap reference voltage generation system includes a common mode voltage generator, a bandgap reference voltage generation circuit, and a switch controller. The bandgap reference voltage generation circuit includes a plurality of transistors having source terminals respectively connected to drain terminals of a plurality of PMOS transistors. The switch controller provides a ground voltage to the bandgap reference voltage generation circuit in a first mode and a common mode voltage to the bandgap reference voltage generation circuit in a second mode. The bandgap reference voltage generation circuit causes the plurality of the transistors to operate in a linear region by providing the common mode voltage to gate electrodes of the plurality of the transistors in the first mode and a saturation region by providing the ground voltage to the gate electrodes of the plurality of the transistors in the second mode.
