RF Noise Modeling of InGaAs Metamorphic HEMTs and MOSFETs
The mechanisms causing the RF noise in InGaAs metamorphic HEMTs and MOSFETs have been investigated and compared. A small signal model for InGaAs metamorphic HEMTs and InGaAs MOSFETs, including an accurate description of the RF noise, is presented. The model is based on a distributed multiport network approach, which is scalable in gate width, the number of gate fingers and covers usual bias points used in amplifier circuits. The noise model is capable of analyzing the sources of noise in InGaAs HEMTs and MOSFETs and their impact on the overall device noise figure. The new extracted MOSFET model is verified on circuit level in the W Band (75 to 110GHz)
