A Tunable Quadrature Oscillator with Only Transconductance Elements and Grounded Capacitors
A novel quadrature oscillator is realised with only transconductance elements (TEs) and grounded capacitors. The realised quadrature oscillator uses only two inverting and two non-inverting transconductance elements, along with two grounded capacitors ...

We demonstrate a top gate Nb capping TFT architecture that induces controlled oxygen out‐diffusion from the IGZO channel. This mechanism generates shallow donor states and enhances electron delocalization, enabling extended percolation pathways. The resulting thin‐film transistors exhibit high mobility, suppressed leakage currents, and strong optical ...

ABSTRACT Layered 2D materials are considered as promising for memristive applications due to their ultimate vertical scalability compared to conventional semiconductor films and pronounced hysteresis properties. Bias‐resolved Raman and Photoluminescence mapping is used to quantify strain from phonon shifts and carrier density from the exciton‐trion ...
