Diode Basics
This device conducts in one direction and blocks in the other.
diode
Uses one diode
half-wave rectifier
Controls BJT operation
base
MOSFET full form
Metal Oxide Semiconductor Field Effect Transistor
Measures amplification
gain
This region in a PN junction has no free carriers
depletion region
Uses four diodes
bridge rectifier
Larger current
collector current
Controls current
Gate
High voltage gain configuration
common emitter
A silicon diode starts conducting around this voltage.
~0.7 V
Reduces ripples
capacitor
Region Used for amplification
active region
What is threshold voltage
Turn ON voltage
Blocks DC, allows AC
coupling capacitor
When reverse voltage exceeds a limit, this occurs
breakdown
This parameter measures the effectiveness of a filter in reducing AC fluctuations
ripple factor
Both junctions forward biased
saturation region
Region acts like resistor
linear region
Type of feedback, when applied to an amplifier, improves stability and reduces distortion
negative feedback
Used for voltage regulation
Zener diode
Preferred for high current
bridge rectifier
Switch regions
cut-off & saturation
This advantage of MOSFETs over BJTs makes them more suitable for large-scale integration
low power consumption
Amplifiers are commonly used in this device to increase sound volume.
