Advanced Materials, EarlyView.Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Switched-transconductance techniques
Electronics Letters, 1993 A new circuit arrangement, described as a switched-transconductance (ST) circuit, comprising a continuous-time linear tunable transconductor and a discrete time current processor is proposed and its theoretical basis described. The approach allows impedance synthesis for tunable precision sampled-data applications.
