Exercise 3.5.1 inverting amplifier
For the inverting amplifier, derive the voltage gain. Use the procedure that was used for the non-inverting amplifier.
Take into account that for the differential gain $A_D$ of the ideal OPV applies: $A_D \rightarrow \infty$.
This also applies: $1/A_D \rightarrow 0$ , but it doesn't always apply ${{C}\over{U_x \cdot A_D}} \rightarrow 0$, for an unknown constant $C$ and a voltage $U_x$!
- What is looking for?
- Number of variables?
- Number of necessary equations?
- Establishing the known equations
- Derivation of the voltage gain
- Welcher der Verstärker (invertierender oder nicht invertierender) hat einen geringeren Eingangswiderstand? Warum?
