A MOSFET differential amplifier such as that shown in Fig. 10.34(a) is biased with a current source I = 400 μA.
The transistors have W/L = 16, k1n = 400 μA/V2,VA = 20 V, Cgs = 40 fF, Cgd = 5 fF, and Cdb = 5 fF. The drain resistors are 10 kΩ each. Also, there is a 100-fF capacitive load between each drain and ground. Find VOV and gm for each transistor.
(a) If the input signal source has a small resistance Rsig and thus the frequency response is determined primarily bythe output pole, estimate the 3-dB frequency fH.
(b) If, in a different situation, the amplifier is fed symmetrically with a signal source of 40 kΩ resistance (i.e., 20 kΩ in series with each gate terminal), use the open-circuit time-constants method to estimate fH.
Write a program to repeat the following tasks continuously.- Turn all four LED lights OFF.- Wait in a loop until one of the push buttons is pressed.- After that, all LEDs must start turning ON and OFF five times with a one-..
Alternatively, the company can outsource ad development at a fee of $20 per ad regardless of the quantity. The current interest rate is 8% per year. What is the breakeven amount, and which alternative is economically better?
Briefly explain the operation of a multiplexer.
A person of weight 100 kg standing on skis 2 m long and 0.10 m wide slides on the 2° mountain slope. at 0°C. Calculate the loss of potential energy when the ski slides a distance equal to its own length. Hence calculate the average thickness of th..

Consider a vertical elevator whose cabin has a total mass of 800 kg when fully loaded and 150 kg when empty. The weight of the elevator cabin is partially balanced by a 400-kg counterweight that is connected to the top of the cabin by cables that ..
1. List three basic technologies used in modern Industrial wireless modems 2. List two issues you should be aware of when deciding on whether you should implement a link at 900 MHz or 2.4 GHz.
For the purposes of this experiment, we will assume this anti-alias filtering is to be done using a recursive low pass filter derived from the Butterworth analogue prototype (using the bilinear transformation).
