A voltage reference using a temperature-dependent current to bias a junction diode [PDF]
, 2013 textBandgap voltage-reference circuits generate an appropriate amount of a voltage that varies proportionately to absolute temperature (called PTAT), to cancel the complementary to absolute temperature voltage variation (known as CTAT) of a current ...

Systematic Design of Bandgap Voltage Reference Using Precomputed Lookup Tables
IEEE Access, 2019 Bandgap voltage references are indispensable in any analog/mixed-signal system. In this paper, we introduce a systematic gm/ID-based procedure to design a CMOS bandgap reference. The proposed iterative methodology relies on one-time-generated precomputed

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...
