Abstract

In this paper, a simple macro model of n-channel MOSFET with dual workfunction gate (DWFG) structure is proposed. The DWFG MOSFET has higher transconductance and lower drain conductance than conventional MOSFET. Thus analog circuit design using the DWFG MOSFET can improve circuit characteristics. Currently, device models of the DWFG MOSFET are insufficient, so simple series connected two MOSFET model is proposed. In addition, a two stage operational amplifier using the proposed DWFG MOSFET macro model is designed to verify the model.
