What is the relationship between the threshold voltage and the device's noise performance, particularly in terms of flicker noise and thermal noise?

The threshold voltage (Vth) of a MOS device plays a crucial role for its operation. At the same time, noise is an intrinsic factor. So how noise (flicker or thermal) change with the change in...

i want to frame the equation of motion of any structural system by energy approach with the help of software like matlab and ansys coding or easy simplified form derivation. Please suggests me something for that

Nikunj Velani

matlab can not make any differential equation, you have to check and make, by your system free body diagram, degree of freedom, etc. and using hooke's law, stress-strain relation, strain energy method, you can find kinetic and potential energy both, any than after you can solve and get differential equation by hamilton`s principle.
