In this paper, a new low-V_DD CMOS bandgap reference circuit with small layout area and low power consumption is proposed. The proposed circuit delivering its output voltage below 1V has its Proportional-To-Absolute-Temperature (PTAT) term compensated by the Complementary-proportional-To-Absolute- Temperature (CTAT) voltage thereby suppressing a change in its output voltage regardless of temperature and V_DD variations. Using a commercial CMOS 0.18-µ m process, the proposed circuit has been verified to be able to save its layout area by 48.7% and the power consumption by 29.9% compared with the previous sub-1-V-output bandgap circuit.
