Steady state behavior analysis of organic thin film transistor (OTFTs) has been thoroughly researched in the past few decades. Yet, this static logic analysis has drawbacks of high power dissipation and high power consumption, and a large number of prerequisites in the number of transistors for the digital logic circuit application. Hence, to overcome these basic fundamental drawbacks of static logic, the dynamic logic study of organic thin film transistor has been analyzed in this paper. The fundamental basic of dynamic logic is a pass transistor for which logic high and logic low model is designed at an operating voltage of 5 V and frequency of 5 kHz. Additionally, the novel approach of analytical model for organic pass transistor (OPT) circuit is included and verified using MATLAB. The transient individualities of organic pass transistor OPT are examined through Atlas 2-D numerical device simulator. The reduction in the power dissipation along with additional voltage scaling and reduction in the clock frequency such as pipelining may further enable the applications into more complex VLSI ICs.
