Abstract.A small size, sub 1V CMOS bandgap voltage reference with the temperature coefficient (TC) of 12ppm/˚C from 0˚C to 100˚C is presented in this paper. The proposed circuit offers several performance advantages over previous bandgap voltage reference circuits. Compared to a conventional structure, it achieves a smaller area by using only two diodes. Also, it can fulfil sub 1V reference voltage by using temperature coefficient of threshold voltage to generate a current proportional to absolute temperature. This is because TC of this current on proposed circuit is bigger than that of conventional structure. Detailed analysis of the proposed bandgap reference is provided, which is simulated using 0.35μm CMOS process. The proposed bandgap reference occupies an active area of 0.0067mm 2 . The simulation results are the voltage reference output voltage of 0.843V and an accuracy of ±0.08%.

“…The conventional bandgap references generally use more than 9 diodes, leading to large die area. And they have voltage reference range from 1.1V to 1.3V [1,2]. This is because of low positive temperature coefficient of current.…”

Abstract. The design challenges of voltage reference generators in CMOS technology have increased over the years in low-voltage low-power CMOS integrated circuits, constituting analog, digital, and mixed-signal modules. The emergence of hand-held power autonomous devices pushes the power consumption limit to nW regime. Along with these confrontations, limited full-scale range of data converters at low supply levels demands accurate reference voltage generators. This paper reviews the allied design challenges and discusses the evolved methodologies to tackle them. This paper also prominently surveys the sub-1 V voltage reference topologies presented in the literature along with classic bandgap based voltage reference topologies. Non-bandgap (only CMOS) based reference architectures are proven to be area-and power-e cient, but always have to be accompanied with auxiliary on/o chip trimming mechanism for high accuracy. We also provide insightful analysis of the voltage reference topologies required by the designers.

Abstract-With ongoing CMOS evolution, the gate-oxide thickness steadily decreases, resulting in an increased radiation tolerance of MOS transistors. Combined with special layout techniques, this yields circuits with a high inherent robustness against X-rays and other ionizing radiation. In bandgap voltage references, the dominant radiation-susceptibility is then no longer associated with the MOS transistors, but is dominated by the diodes. This paper gives an analysis of radiation effects in both MOS devices and diodes and presents a solution to realize a radiation-hard voltage reference circuit in a standard CMOS technology.
