![[op-amp-basic-schematic-symbol.svg]]
The operational amplifier has a very high input impedance which makes it very good for amplifying low voltage signals.
Basically the OpAmp is a function like this:
$\displaystyle Y = A_v (X_1 - X_2)$
Where:
$$
\begin{flalign}
&Y = \text{Output Voltage}&\\\
&A_v = \text{Open Loop Gain}\\
&X_1 = \text{Input V1 (Non Inverting Input)}\\
&X_2 = \text{Input V2 (Inverting Input)}\\
\end{flalign}
$$
# Regions
Op Amps functions in different regions, just like diodes, and transistors.
![[op-amp-regions.png|400]]
**Linear Region**
This is how the Op-Amp normally functions.
**Saturation Region**
When the output of the op-amp would be higher than $+V_{CC}$ or lower than $-V_{CC}$ the output value is clamped to those values.
In real life OpAmps have $A_V$ values as high as $10^8$ or $10^9$ due to this even very small input voltages would quickly leave the linear region. That is why we need
**Negative Feedback**
To use negative feedback we connect the output of the OpAmp to one of its inputs. This connection is modified by a *feedback factor* ($\beta$) which can be in the range $0 \le \beta \le 1$.
Due to this feedback the new formula for the output $V_O$ is now:
$$
\begin{flalign}
&V_o = A_V * V_\Delta&\\\
\\
&V_- = \beta * V_o\\
&\text{Now we can say that }V_\Delta \text{is equal to:}\\
&V_\Delta = V_+ - \beta *V_o &| \textit{ Solve for }V_o \\
&V_o = \frac{V_+ - V_\Delta}{\beta}
\end{flalign}
$$

There are two types of transistors:
# Bipolar Junctions Transistors (BJT)
![[bipolar-junction-transistor|200x]]
The current flowing in from Base controls the much larger current flowing between Collector and Emitter.
## Rules for NPN Transistors
**1. Polarity**
The collector must be more positive than the emitter.
**2. Junctions**
The base$\rightarrow$emitter and base$\rightarrow$collector connections behave like diodes.
**3. Maximum Ratings**
Any transistor has maximum ratings for $I_C$ ,$I_B$ and $V_{CE}$ that should not be exceded.
**4. Current Amplifier**
When rules 1-3 are obeyed, $I_C$ is roughly equivalent to $IB$ and can be written like:
$\displaystyle I_C = \beta I_B$
In the following example circuit we can see that for a $\beta$ of 100 the Ic current is aroung 100 times higher than the base current.

## NPN vs PNP Transistors
The names come from the way they are constructed
![[bjt-transistors.png]]
![[transistors-pnp-npn]]
# Transistor Modes
## Saturation
In this mode the transistor acts like a short circuit and current flows freely from emitter to collector.
## Cut-Off
In this mode the transistor acts like an open circuit and no current flows from emitter to collector.
When $V_C > V _B < V_E$ then the transistor acts in Cutoff Region
## Active
The current from collector to emitter is proportional to the current flowing into the base.
# Field-Effect Transistors (FET)
![[field-effect-transistor|200x]]

# L - Topology
The L filters consist of two reactive elements, one in series with the signal and one in parallel to it.
**RC Filters** are very cheap and easy to build but are only suited for low power applications as there is a resistor in series with the signal. Also the resistor may introduce thermal noise to the signal.

\begin{flalign}
&I = \frac{V}{Z}&\\\
&Z = R^2 + (X_C-X_C)^2&\\
&X_C = \frac{1}{\omega C} &\\
&X_L = \omega C &\\

Lets put in some numbers
$$
\begin{flalign}
&X_C = \frac{1}{2\pi*50*0.0001} \approx 31.830\ohm &\\\
&X_L = 2\pi*50*0.15 \approx 47.123\ohm&\\
&Z = \sqrt{12^2+(31.830-47.123)^2} \approx 19.4\ohm\\
&I = \frac{100}{19.439} \approx 5.14A
\end{flalign}
$$
Now lets finally calculate the voltage drops across all the components
$$
\begin{flalign}
V_R = 5.14*12 &\approx 61.68V&\\\
V_L = 5.14*47.13 &\approx 242.24V\\
