Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.

This review surveys organic electrochemical transistors as core building blocks for energy‐autonomous bio‐integrated electronics. We outline device physics, OMIEC materials, and electrolyte effects that enable sub‐volt, high‐gain operation, and discuss direct coupling with mechanical, thermal, and optical energy harvesters to realize battery‐free ...

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 ...

Harnessing the VO2 Phase Transition for Automatic Gain Control in Transimpedance Amplifiers
A nanoscale VO2‐based volatile switch integrated into a transimpedance‐amplifier feedback loop dynamically lowers gain when input current rises, preventing saturation and extending dynamic range. Rapid self‐recovery restores high sensitivity without external reset circuitry.

Prediction of GaAs metal–semiconductor field-effect transistor parameter spread
It is shown that for Schottky-barrier field-effect transistors based on three-layer GaAs structures (film – buffer layer – substrate), the parameter spread caused by the nonuniform distribution of deep centers across the wafer can be characterized by a ...

Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology
Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures
