Using Multisim to simulation the bellow Question , if you dont have Multisim you can any simaulator

1. Exercise 5.27 p.421 (Separate DC from AC Analysis

2.Simulation: Apply 10mV signal at the input.

ii.Find the maximum output swing using the simulator (compare between them).

Note: show the input and output voltage plots in the same graph!.

5.27 A CS amplifier utilizes a MOSFET biased at ID 0.25 mA with V 0.25 V and R 20 k2 OV The device has V 50 V. The amplifier is fed with a source having Rsig 100 kn, and a 20-kn load is connected to the output. Find R Avo, Ro, H and Go. If to maintain reasonable linearity, the peak of the input sine-wave signal is limited to 10% of (2 Vor) what is the peak of the sine- wave voltage at the output? Ans. oo; 36.4 VIV; 18.2 km: -19 VN: 9 VN: 0.95 V

Explanation / Answer

As per chegg policy only one part i.e.second question is done.

Solution:-

Use an instrumentation amplifier like this one.

Since we want to amplify 10mV to 0-5V, 5V/10mV = gain of 250. Use the datasheet to select a gain resistor. For my example, G = 1 + (100k/Rg), so Rg = 100k/(G-1) for 402 Ohms. These values need to be pretty exact, and when in doubt make it a little bigger and sacrifice a little span. Since we want 0-5V, we'll want to set the reference voltage to 2.5V since that is the middle of the span. Use a reference diode for that.
