我们证明了一个显着的改善，在闭环有机放大器的增益通过系统地控制阈值电压（VTH）与双栅极结构。使用的双聚对二甲苯电介质的结果在工作电压低至4 V与电源电压（VDD）为2 V的双栅极结构被引入用于控制的晶体管的VTH和逆变器的开关电压。在VDD值为2 V时，逆变器的最大直流增益为29.3 dB。此外，电路的开关电压可以从0 V控制到VDD，而不会显著降低性能。系统地研究了VTH控制对闭环放大器的影响，通过将开关电压调节到VDD的一半，闭环增益得到了高达18.8 dB的显著增益改善。
We demonstrate a significant improvement in the gain of closed-loop organic amplifiers by systematically controlling the threshold voltage (VTH) with double-gate structures. The use of an ultrathin parylene dielectric results in an operating voltage as low as 4 V with a supply voltage (VDD) of 2 V. Double-gate structures were introduced for controlling VTH of the transistor and the switching voltage of the inverter. The maximum dc gain of the inverter was recorded as 29.3 dB at a VDDvalue of 2 V. In addition, the switching voltage of the circuits can be controlled from 0 V to VDDwithout a significant performance degradation. The effects of the VTH control on the closed-loop amplifier were systematically investigated and a significant gain improvement of up to 18.8 dB was demonstrated in the closed-loop gain by adjusting the switching voltage to half of VDD.
