Active Comb Filter Using Operational Transconductance Amplifier [PDF]
A new approach for the design of an active comb filter is proposed to remove the selected frequencies of various signals. The proposed filter is based on only OTAs and capacitors, hence suitable for monolithic integrated circuit implementation. The workability of the circuit is tested using PSPICE for test signals of 60, 180, 300, and 420 Hz as in ECG ...

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

Active-Only Sinusoidal Oscillator Circuits
Two new active-only sinusoidal oscillator circuits are proposed. The first circuit uses one current feedback operational amplifier (CFOA) and four operational transconductance amplifiers (OTAs). The second circuit uses only four OTAs.

A Standard-Cell-Based CMFB for Fully Synthesizable OTAs
In this paper, we propose a fully standard-cell-based common-mode feedback (CMFB) loop with an explicit voltage reference to improve the CMRR of pseudo-differential standard-cell-based amplifiers and to stabilize the dc output voltage.
