2 SPECIAL PURPOSE DIODES
Photo diode , solar cell
Base=?
emitter - collector
purspose of filter capacitor
to remove ripple or ac component
biasing method for operating transistor as amplifier
emitter-base junction =forward bias
collector base junction=reverse bias
current amplification factor
B
rectification
converting AC voltage to DC
Advantages of photodiode
High speed
light weight and compact
low cost
quick response to light
disadvantages of photodiode
temperature dependent
Advantages of full wave rectifier
utilizes both cycles.
higher efficiency
less ripple
