Two circular plates, each with a radius of 3.22 cm, have equal and opposite charges of magnitude 1.652 μC. Calculate the electric field between the two plates. Assume that the separation distance is small in comparison to the diameter of the plates. electric field: The plates are slowly pulled apart, doubling the separation distance. Again, assume the separation distance remains small in comparison to the diameter of the plates. What changes occur with the electric field between the plates? The electric field increases by a factor of 2. The electric field decreases by a factor of 4. The electric field decreases by a factor of 2. The electric field increases by a factor of 4. The electric field stays the same.

Consider the active-loaded MOS differential amplifier of Fig. 1 operates with a bias current I of 100uA. The NMOS transistors are operated at Vov = 0.2 V and the PMOS devices at |Vov| = 0.3 V. The Early voltages are 20 V for the NMOS and 12 V for the PMOS transistors. Find Gm, RO, and Ad. For what value of load resistance is the gain reduced by a factor of 2? Figure. 1

Statement I: In a MOS cascode amplifier, the cascaded transistor is required to increase the output impedance by a factor of 40. If overdrive voltage (Vov = VGS − VTH) of the cascaded transistor is 0.2 V. Then, channel length modulation parameter (λ) is 0.25 V−1. Statement II: If we have K = gm2 ro2 = 40, then λ can be obtained as 1 λ = KVov 2, which results in λ = 0.25 V−1. Both statement I and statement II are true, and statement II is not the correct explanation for statement I. Both the statements are false. Statement I is true, and Statement II is false. Both statement I and statement II are true, and statement II is the correct explanation for statement I.
