Concerning formula for Memristance

dw(t)/dt = mu_v R_on/D i(t)
=> w(t) = mu_v R_on/D (q(t) + q_0) taking only q_0 = 0 solution:
w(t) = mu_v R_on/D q(t)

M(q) = R_on w(t)/D + R_off (1-w(t)/D)
M(q) = mu_v R_on^2/D^2 q(t) + R_off (1 – mu_v R_on/D^2 q(t))

isn’t the term: (mu_v R_on^2/D^2 q(t)) missing in the formula given for M(q) at 14:56, or did I miss something?

In:
The missing memristor found
Dmitri B. Strukov, Gregory S. Snider, Duncan R. Stewart & R. Stanley Williams
published in nature vol 453

it is explained that the term involving the factor (R_on^2) is neglected because R_on << R_off

3. ASH

they have considered Ron<<Roff

so they have neglected the term.

hope u got it
