Two low-power voltage reference cells for a system on-chip design are presented in this report. Both cells utilize a combination of standard transistors to produce an output voltage near 1 volt. Choosing the appropriate design procedures can aid in minimizing the temperature coeﬃcient (TC) of the output reference voltage coming out of the cell. One circuit, covered ﬁrst, is currently being fabricated on a standard 0.5 µm chip complementary metal oxide semiconductor (CMOS) process, while the other is still in the designing stage. The ﬁrst one has a TC of 86 ppm/◦C with a reference voltage of 1.10 V while consuming 1.25 µW of power by simulation. The second voltage reference cell is aimed for a lower TC, and power consumption approximately 37 ppm/◦C and 2 nW in simulation. Additionally, ideas to improve the circuits will be explored, and the layout of the ﬁrst cell will be presented in this paper.
