Voltage references are key elements in analog and mixed-mode circuits. They determine the overall accuracy in many data-acquisition systems. The accuracy of our smart temperature sensor is also mainly dependent on the quality of its voltage reference.

5.7 A 29nW bandgap reference circuit
2015 IEEE International Solid-State Circuits Conference - (ISSCC) Digest of Technical Papers, 2015Bandgap references (BGRs) are widely used to generate a temperature-insensitive reference voltage determined by the silicon bandgap. the BGR generally utilizes PN diodes to generate both of proportional-to-absolute-temperature (PTAT) and complementary-to-absolute-temperature (CTAT) quantities and combines them to eliminate the temperature dependency ...

For many years bandgap references have been used as voltage references in various fields of application; for instance, in DA converters [1], automotive industry [2] or battery-operated DRAMs [3]. All of the bandgap references used in this diverse variety of applications are based on the idea of Hilbiber in 1964 [4]. After his publication, a vast number

Low Voltage Buffered Bandgap Reference
8th International Symposium on Quality Electronic Design (ISQED'07), 2007We propose a new bandgap reference topology for supply voltages as low as one diode drop (~0.8V). In conventional low-voltage references, supply voltage is limited by the generated reference voltage. Also, the proposed topology generates the reference voltage at the output of the feedback amplifier.

Design of the 1.0V bandgap reference on chip
2015 IEEE 11th International Conference on ASIC (ASICON), 2015This paper proposes the design method of the 1.0V bandgap reference circuit on chip based on the bandgap reference nucleus. The voltage reference which is lower than 1.25V can be obtained with zero temperature coefficients under normal temperature, in parallel with small resistances near the bipolar transistors.

A resistorless switched bandgap reference topology
2013 IEEE 4th Latin American Symposium on Circuits and Systems (LASCAS), 2013This work presents a novel Switched-capacitor Bandgap Reference circuit using no resistors at all. The negative drift VEB and the positive drift VT voltages are generated by the same PNP bipolar transistor. A switched-capacitor circuit stores and processes these voltages, generating the bandgap reference voltage in only 4 clock phases.

A CMOS bandgap reference without resistors
2000 IEEE International Solid-State Circuits Conference. Digest of Technical Papers (Cat. No.00CH37056), 2002Bandgap references add the forward bias voltage across a pn diode with a voltage that is proportional to absolute temperature (PTAT) to produce an output that is insensitive to changes in temperature. The relative weighting of the voltages added is usually adjusted by trimming the ratio of two resistors.

A precision CMOS bandgap reference
IEEE Journal of Solid-State Circuits, 1984The simple circuit uses naturally occurring vertical n-p-n bipolar transistors as reference diodes. Use is made of p-tub diffusions as temperature-dependent resistors to provide current bias, and an op-amp is used for voltage gain. Only two reference diodes, three p-tube resistors, and one op-amp are necessary to produce a reference with fixed voltage ...

A bandgap reference in 65nm CMOS
2016 IEEE International Nanoelectronics Conference (INEC), 2016A bandgap reference circuit with voltage and current output is presented. Operational transconductance amplifier(OTA) have been used for a higher DC power supply rejection rate(PSRR) under small gate length of MOSfet. Both telescopic and folded OTA and low threshold voltage MOSfet have been used to ensure the circuit at suitable operation points under ...
