“…However, they are not suitable for our purpose because they need large resistors with high resistance for low-current operation in the subthreshold region. Buck and others proposed a new CMOS bandgap reference circuit without the use of resistors [4]. We modified their circuit to operate in the subthreshold region and to generate a floating millivolt reference.…”

“…As a step toward low voltage and low power, a reference circuit is developed which can operate with an ultra-low current in the subthreshold region of MOSFET [2]. Unfortunately, the subthreshold region of MOSFET circuits commonly employs high values of resistors, while the application of polysilicon resistors not only increases the area and cost but also worsens the coupling effect of the substrate noise, so some structures without using resistors have been proposed [4].…”

Abstract:A novel high precision high order curvature-compensated bandgap reference (BGR) is presented in this paper designed using the subthreshold current of self-cascode transistors in standard digital 0.18 μm CMOS process. Simultaneously its temperature coefficient is typically 4.6 ppm/ • C in the temperature range of −25 to 120 • C with a supply current of 17.25 μA. A power supply rejection ratio (PSRR) of −51 dB is achieved while the layout area is no more than 0.0022 mm 2 . Keywords: CMOS, voltage reference, subthreshold, high-order curvature -compensation, high PSRR, self-cascode transistor Classification: Integrated circuits Chen, X. Ming, and B.

This article explores the main tradeoffs in design of power and area efficient bandgap voltage reference (BGR) circuits. A structural design methodology for optimizing the silicon area and power dissipation of CMOS BGRs will be introduced. For this purpose, basic equations of the bandgap circuit have been adapted such that can simply be applied in the optimization process. To improve the reliability of the designed circuit, the effect of amplifier offset has been also included in the optimization process. It is also shown that the minimum achievable power consumption and area are highly depending on the fabrication process parameters especially sheet resistivity of the available resistors in the technology and also the area of bipolar transistors. The proposed technique does not depend on a special process and can be applied for designing bandgap reference circuits with different topologies.
