AEC Flashcards
Are materials with electrical properties that lie between conductors and insulators
Semiconductors
The two most commonly usef semiconductive materials
1) Silicon
2) Germanium
Silicon has __ protons in its nucleus while Germanium has __ protons
Silicon - 14 protons
Germanium - 32 protons
When a certain atoms come together to form a solid material, they arrange themselves in a fixed, repeating pattern known as?
Crystal Lattice
What are the 4 advantages of silicon over germanium
1) Higher Bandgap
2) Better Thermal Stability
3) Lower Intrinsic Carrier Concentration
4) Radiation Hardness
To enhance conductivity, impurities are added through a process called?
Doping
This is formed by adding pentavalent impurities with five valence electrons
N-Type Semiconductors
This is formed by adding trivalent impurities with three valence electrons
P-Type Semiconductors
It allows precise control over conductivity by adjusting the number of impurity atoms, making these materials fundamental to electrons
Doping
It is a two-terminal semiconductor device that allows current to flow in one direction
Diode
Is the conditon that allows the current to flow through a diode
Forward Bias
Is a condition that prevents current flow through the diode
Reverse Bias
Are essential components in all DC power supplies that operate from an AC voltage source
Diode Rectifier
It converts the AC input voltage into a pulsating DC voltage.
Rectifier
It is used to eliminate fluctuations in the rectified voltage.
Capacitor Filter
is a circuit designed to maintained a constant DC output voltage, even when there are variations in the input line voltage or changes in the load. Regulators can range from simple devices to more complex integrated circuits.
Regulator
This diagram represents the circuit or device that the power supply is designed to power. It consumes the DC voltage and current provided by the power supply
Load
These components oppose the flow of the electric current in a circuit
Resistors
They are used for filtering signals, smoothing voltage fluctuations, and storing temporary electrical charge
Capacitors
These components oppose changes in current flowing through them
Inductors
