In Exercise, the body effect was ignored. If the body effect is considered, will IDS2 be equal to, greater than, or less than IDS1? Explain.

Exercise

Show that the current through two transistors in series is equal to the current through a single transistor of twice the length if the transistors are well described by the Shockley model. Specifically, show that IDS1 = IDS2 in Figure when the transistors are in their linear region: VDS < VDD – Vt, VDD > Vt (this is also true in saturation). Hint: Express the currents of the series transistors in terms of V1 and solve for V1.
