hi guys, i need some help in my Electronics Lab project.
The project is as follows:
Design an Amplifier that meets a set of specifications:
1. |Av|=10 plus minus 2
2. Rin>=50 kohm
3. Ro<=50 ohm
4.Q point is stable within plus minus 10%
5.Vo is not distorted
6.Fl<=20Hz
7.Fh>=100kHz
avaialbe resistors:
100,220,330,390,470,680,820 ohm
1,2.2,3.9,4.7,6.8,8.2 kohm
10,22,39,68,82,100,220,470 kohm
1 mohm
0.1,0.68 microF
Vcc=15V
Vs=0.1sinwt , Rs = 50ohm
RL=2.2 kohm
using NPN BJT (BC 107) transisstors.
My solution:
judging from Ro<=50 ohm, we need 2 stage amp , one is Common Emiiter for the gain, and another is common collector for the buffer.
i came up with a design, unfortunately , i cant tell if its correct or not, so all im asking if anyone can check it for me, and to coorect anything wrong with my design.
