The distortion and linearity behaviour of MOSFETs is imperative for low-noise applications and RFICs design. In this paper, an extensive study on the RF-distortion and linearity behaviour of Laterally Amalgamated DUal Material GAte Concave (L-DUMGAC) MOSFET is performed and the influence of technology variations such as gate length, negative junction depth (NJD), substrate bias, drain bias and gate material workfunction is explored using ATLAS device simulator. Simulation results reveal that L-DUMGAC MOSFET significantly enhances the linearity and intermodulation distortion performance in terms of figure of merit (FOM) metrics: VIP2, VIP3, IIP3, IMD3 and higher order transconductance coefficients: gm1, gm2, gm3, proving its efficacy for RFIC design. The work, thus, optimize the device’s bias point for RFICs with higher efficiency and better linearity performance.
