Common base configuration:
for pap transistor connection for common base operation is as follow: common base means base is common to both input and output side of configuration. we use current direction in the direction in the direction of holes movement for common base input or driving point characters for is transistor is the plot of the i.e. vs vibe for various level of output voltage . Output or collector characteristics for a common base configuration for various level of i.e. can be plotted as shown in figure
In the active reason the collection base junction is revised biased while the base emitter junction is forward biased.
When i.e.=0, the collector current is simply due to the reverse saturation current
(Note)L1) in the cut off region the collector base and collector emitter junction base t of a transistor are the both reverse biased.
(11) in saturation region the collector base and base emitter junction bad are forward biased .
Alpha: in de mode the level of ice and i.e. dude to majority carriers the relative by a quantity called alpha and is defined.
a) What is meant by Ripple Voltage? Measure the Ripple Voltage Amplitude, Frequency and DC Offset b) Describe how Ripple Voltage could be decreased.
Q. Differential amplifier to eliminate the common-mode voltage? The transducer in some cases may have a local ground that cannot be disconnected. In such a case, a separate gro
Q. A charge variation with time is given in Figure. Draw the corresponding current variation with time.
charges of +2q and -4q are fixed a distance d apart as in figure_2(a).find electric field at the point A ,B and C (b) sketch roughly the electric field lines.
The magnetic field can be supplied by coils supplied from the output of the generator itself. This is known as self-excitation.There are three ways that the field coils can be conn
Q. Two 1150:115-V transformers are to be inter connected for (a) 2300:230-V operation, and (b) 1150:230-V operation. Show the interconnections and appropriate polarity markings.
