capacitor
$begingroup$ @PICyourBrain, continuing on from Gabriel''s comment. The purpose of the internal diode is to prevent any pin going higher than Vcc, In the old days of CMOS, over-driving pins would cause strange parasitic effects within the silicon wafer, especially you could trigger a parasitic PNPN junction somewhere that is basically a thyristor (SCR) that

Characterization of Capacitor-Loaded Transmission Line for Phase
The used transmission line is composed of common microstrip lines that are loaded with capacitors placed at regular intervals. A theoretical approach shows that the transmission phase on the capacitor-loaded microstrip line depends on the capacitances of the loading capacitors, thus it is beneficial for configuring a phase shifter circuit.

through an inductor or voltage across a capacitor. A transmission line is a wire with a uniform goemetry along its length: the capacitance and inductance of any segment is proportional to its length. We represent as a large number of small inductors and capacitors spaced along the line. The signal speed along a transmisison line is predictable.

6 FAQs about [Line with capacitors]
What if two series connected capacitors are equal?
If the two series connected capacitors are equal and of the same value, that is: C1 = C2, we can simplify the above equation further as follows to find the total capacitance of the series combination.
How do capacitors in series work?
When adding together Capacitors in Series, the reciprocal ( 1/C ) of the individual capacitors are all added together ( just like resistors in parallel ) instead of the capacitance’s themselves. Then the total value for capacitors in series equals the reciprocal of the sum of the reciprocals of the individual capacitances.
What does a capacitor sign mean?
Another typical capacitor sign is a rectangle with a straight line on one end, symbolizing the positive terminal. The rectangle's negative terminal is usually a curved line or no line. The symbol for a fixed capacitor depends on the capacitor type and the circuit diagram designer or engineer's preference. 1. Disc Ceramic Capacitors
What is a capacitive voltage divider network?
With series connected capacitors, the capacitive reactance of the capacitor acts as an impedance due to the frequency of the supply. This capacitive reactance produces a voltage drop across each capacitor, therefore the series connected capacitors act as a capacitive voltage divider network.
What happens if series capacitor values are different?
However, when the series capacitor values are different, the larger value capacitor will charge itself to a lower voltage and the smaller value capacitor to a higher voltage, and in our second example above this was shown to be 3.84 and 8.16 volts respectively.
What is a circuit diagram symbol for a fixed capacitor?
Circuit diagram symbols for fixed capacitors vary by kind. A fixed capacitor is usually represented by two parallel lines whose length represents its capacitance. Another typical capacitor sign is a rectangle with a straight line on one end, symbolizing the positive terminal. The rectangle's negative terminal is usually a curved line or no line.
