A sub 1V bandgap reference circuit [PDF]

, 2006
This thesis proposes a novel technique for a low supply voltage temperature-independent reference voltage. With the scaling of supply voltages, the threshold voltages don’t scale proportionally and thus low supply reference circuits have replaced the ...

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

Advanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Advanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

A Power and Area Efficient CMOS Bandgap Reference Circuit with an Integrated Voltage-Reference Branch

, 2019
This work presents a compact and low power bandgap voltage reference design using self-biased current mirror circuit. This design eliminates the standard complementary-to-absolute-temperature (CTAT) bipolar device in the voltage-reference branch ...

Regulating Phase Evolution and Crystallization Dynamics Enables Low Open‐Circuit Voltage Deficit in Wide‐Bandgap Cu2ZnSnS4 Solar Cells

Advanced Materials, EarlyView.
Bilayer composition‐modulated sulfurization (BCMS) regulates Cu redistribution in solution‐processed Cu2ZnSnS4, suppressing Cu2SnS3 and favoring the direct transformation pathway, while transforming the crystallization from surface‐dominated growth to a more synchronized process.

Research Progress on Bandgap and Non-Bandgap Reference Circuits

Academic Journal of Science and Technology
Bandgap reference (BGR) circuits could provide stable, temperature-insensitive reference voltages or currents that are essential to system-level designs. These circuits are extensively employed in critical applications including voltage regulators, oscillators, and analog-to-digital converters (ADCs).

A Sub-1V, Micropower Bandgap Reference

, 2012
Bandgap references are used in many ICs to produce ‘stable’ and ‘temperature-independent’ voltage. This thesis describes a sub-1V bandgap reference in 40 nm and 0.16 µm CMOS technologies that is functional from -40 oC to 125 oC.
