Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, Volume 10, Issue 21, 9 November 2026.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Low‐Frequency Noise and Stability in Electrolyte‐Gated Nanoscale Silicon Field‐Effect Transistor Sensors

Small Methods, Volume 10, Issue 21, 9 November 2026.
Electrolyte‐gated nanoscale silicon field‐effect transistor sensors provide exceptional charge sensitivity and direct electrical readout. However, their sensing accuracy is fundamentally limited by low‐frequency noise and baseline drift. This review examines the origins of noise and drift in these sensors, summarizes the key mitigation strategies, and ...

The design of an operational transconductance amplifier (OTA)

, 2017
Operational amplifiers are commonly used in analog circuit designing, especially operational transconductance amplifier (OTA)which is used to convert input voltage signal into an output current. However, OTA could only drive capacitive load, therefore an
