Abstract
Recently, molecular devices with interesting behaviour like conductance, switching, rectification, gate modulation and negative differential resistance were realized. In this paper we propose a method to model hierachical logic circuits based on Oligo-Phenylene Vinylene (OPV) molecular field effect transistor (MOLFET). The modeling is based on a device level spice equivalent model and on a versatile language (VHDLAMS) assuring a hierarchical description and a successive approximation approach. Elementary logic blocks as well as a more complex circuit (RCA) were designed and simulated with a crossbar organization, both in a NMOS-like and in a CMOS-like configuration.
