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.

Schottky Barrier Engineering in n‐Type Organic Source‐Gated Transistors Enabling High Conductance

Advanced Materials Technologies, EarlyView.
This study introduces a modified source electrode architecture for n‐type organic source‐gated transistors (OSGTs). By integrating Schottky and Ohmic contact regions, the design achieves a thinner depletion envelope, enhancing mobility nearly tenfold and reducing threshold voltage.

Operational Transconductance Amplifier-Based Electronically Controllable Memcapacitor and Meminductor Emulators

Journal of Circuits, Systems and Computers, 2021
In this paper, two simple circuits are presented to emulate both memcapacitor and meminductor circuit elements. The emulation of these components has crucial importance since obtaining these high-order elements from markets is difficult when compared to resistor, capacitor and inductor.

Printable Conductive Hydrogels for Electrochemical Biosensing and Soft Bioelectronic Interfaces

Advanced Science, EarlyView.
Flexible, conductive hydrogels that integrate printability, mechanical tunability, biocompatibility, and electronic performance remain challenging to achieve. Here, we develop 3D‐printable poly(ethylene glycol)–poly(pyrrole)‐ hydrogels with tissue‐like mechanics, high cytocompatibility, and robust electrochemical function.

Universal three input and one output current-mode filter withoutexternal passive elements [PDF]

, 1997
A new current-mode universal filter is proposed. The filter uses only operational amplifiers and operational transconductance amplifiers (OTAs) and can realise lowpass, highpass, bandpass, notch and allpass responses without changing circuit topology ...

Floating-Gate Operational Transconductance Amplifier

International Journal of Information and Electronics Engineering, 2013
A configuration of operational transconductance amplifier (OTA) based on floating-gate MOSFETs for low- power, low-voltage, and low-frequency applications is presented in this paper. The main features of the proposed OTA are design simplicity and rail to rail input voltage at supply voltage of ±0.5 V.
