Circuit Design and Experimental Verification of Low-voltage Organic Field-effect Transistor-based Common Source Amplifier

The request for efficient circuit design and solution/printing-compatible manufacturing of high performance low-voltage amplifiers have gradually become more and more urgent. In this work, a transconductance efficiency based circuit design methodology is introduced for quick sizing of an organic low-voltage common source amplifier, which is further verified by a fully solution-processed amplifier circuit. The amplifier is developed based on a low trapstate density OFET (LTDOFET) technology and demonstrated reliable amplification of the input small signal.
