Abstract :
The low-frequency noise in asymmetric MOS transistors with graded channel doping from the source to the drain can be partitioned by assuming a series connection of two or more transistors along the device´s channel length. The partition explains the noise overshoot at gate biases around the threshold voltage of the composite device. Expressions for the input-referred gate noise voltage are obtained and verified.
