Design an interface circuit that will allow i = 12.5mA current to be given to 1200 load and Rout = 2400 as follows (R = 1200 İs = 100mA g = 0.001)?
The interface will be a voltage divider coupling.
- Output resistance condition sets the value of R2:
Find the value of R1
The output voltage is:
Then, the current on R1 is:
To find R1, calculate the value of voltage VS:
Using voltage nodes equation on Vs:
eq 1
Notice that V1 and V2 are voltage dividers woth the same values, V1 and V2 are expected to be V1=V2, then no current flows through the resistance that connects them and:
In eq1
Solve for Vs:
To find R1, apply Ohm's Law:
Design an interface circuit that will allow i = 12.5mA current to be given to 1200...
