Gate voltage dependence of channel length modulation for InGaAs n-channel MOSFETs

This paper describes gate voltage dependence of channel length modulation for InGaAs n-channel MOSFETs. The gate voltage dependence of the channel length modulation is extracted from experimental current voltage characteristics. It is found that InGaAs n-channel MOSFETs show the gate voltage dependence of channel length modulation. To investigate the effects of the V
_G
dependence of λ on the current voltage characteristics, the analytical MOSFET model is compared with the experimental data. It is found that the V
_G
dependence of λ is essential in simulation of the current voltage characteristics for InGaAs n-channel MOSFETs.
