If a 0.02-V signal is superimposed on VGS, find the corresponding increment in collector current by evaluating the total collector current iD and subtracting.
An NMOS amplifier is to be designed to provide a 0.20-V peak output signal across a 20-k_ load that can be used as a drain resistor.
In the table below, for MOS transistors operating under a variety of conditions, complete as many entries as possible.
An NMOS technology has µnCox = 250 µA/V2 and Vt = 0.5 V. For a transistor with L = 0.5 µm, find the value of W that results in gm = 2 .
What is the voltage gain vo/vi ? What do VD and the gain become for I increased to 1 mA?
Find the small-signal model parameters (gm and ro) for both an NMOS and a PMOS transistor having W/L = 10 µm/0.5 µm and operating at ID =100 µA.
That is, assume these values, and verify that they are consistent with the values of the circuit components and the device parameters.

A boat moves relative to water with a velocity which is n = 2.0 times less than the river flow velocity.
A car is behind a truck going 25 m/s on the highway. The car's driver looks for an opportunity to pass, guessing that his car can accelerate at 1.0m/s2.
A car moving at 95 km/h passes a 1.00-km long train travelling in the same direction on a track that is parallel to the road
A car starts moving rectilinearly, first with acceleration w = 5.0 m/s2 (the initial velocity is equal to zero), then uniformly, and finally, decelerating
A cannon fires successively two shells with velocity vo = 250 m/s; the first at the angle ?1 = 60° and the second at the angle ?2 = 45° to the horizontal
A cannon and a target are 5.10 km apart and located at the same level. How soon will the shell launched with the initial velocity 240 m/s
