Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Self-Biasing High Precision CMOS Current Subtractor for Current-Mode Circuits

Advances in Electrical and Computer Engineering, 2013
In this study, a novel, differential pair based, high performance and high bandwidth current subtractor is proposed. Very low equivalent impedances are obtained at input ports n and p by using source follower transistors.

Low-distortion low-voltage operational transconductance amplifier [PDF]

Electronics Letters, 2008
A new operational transconductance amplifier (OTA) is proposed, which is based on the flipped voltage follower and source degeneration techniques. The OTA is simulated in a standard TSMC 0.18 μm CMOS process with a 1.8 V supply voltage. The simulation results show that the total harmonic distortion of the proposed OTA is less than 1% up to 0.85 Vp-p.

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...
