Abstract

The drain current modeling of antiambipolar thin film transistors (TFTs) in subthreshold and above-threshold regimes is presented. The drain current expressions of the n-type and p-type unipolar TFTs are extended to describe the electron current and hole current for antiambipolar TFTs, respectively. Applying the rule “smaller than the smallest” with the drain-source voltage-dependent empirical parameter, the drain current model for the antiambipolar TFTs is developed. The model is implemented in the circuit simulator using the Verilog-A programming language. A ternary inverter, which consists of antiambipolar TFT, p-type unipolar TFT, and n-type unipolar TFTs, is demonstrated.

阈下和阈上条件下反双极性tft的漏极电流模拟

提出了反双极性薄膜晶体管在亚阈值和高于阈值状态下的漏极电流模型。将n型和p型单极tft的漏极电流表达式扩展为分别描述反双极tft的电子电流和空穴电流。利用漏极-源极电压相关经验参数的“小于最小”原则，建立了反双极性TFTs的漏极电流模型。该模型采用Verilog-A编程语言在电路模拟器中实现。演示了一种由反双极性TFT、p型单极TFT和n型单极TFT组成的三元逆变器。
