Levels of part c are reasonably close but as expected due to level of applied voltage E. Click here to sign up. For the positive region of vi: The voltage divider configuration should make the circuit Beta independent, if it is well designed.

Beta did increase with increasing levels of IC. The spacing between curves for a BJT are sufficiently similar to permit the use of a single beta on an approximate basis to represent the device for the dc and ac analysis.

For either Q1 or Q2: Both teiria are 1.

In our case, the scope measures better than the signal generator. Theoretically, the most stable of the two collector feedback circuits should be the one with a finite RE. Shunt Voltage Regulator a. Computer Exercises PSpice Simulation However, for non-sinusoidal waves, a true rms DMM must be employed. In general, the voltage-divider configuration is the least sensitive with the fixed-bias the most sensitive. Such may not be entirely true. Help Center Find new research papers in: For this particular example, the calculated percent deviation falls well within the permissible range.


The heavy doping greatly reduces the width of the depletion region resulting in lower levels of Zener voltage.

Band-Pass Active Filter c. Log In Sign Up. Skip to main content. In addition, the drain current has reversed direction. Thus it can be seen that the given formulation was actually a minimum value of the output impedance.

See Circuit diagram 9. The conditions stated in previous answer define a positive edge triggered flip flop as defined in the first paragraph of Part 1. Hence, so did RC and RE. The LED generates a light source in response boglestad the application of an electric voltage.

Note that an angle of Darlington Input and Output Impedance a. Experimental Determination of Logic States.

See Probe plot The frequency of 10 Hz of the TTL pulse is identical to that of the simulation pulse. A p-type semiconductor material is formed by doping an intrinsic material with acceptor atoms having an insufficient number of electrons in the valence shell to complete the covalent bonding thereby creating a hole in the covalent structure.

The overall frequency reduction of the output pulse Teofia The frequency at the U2A: In equation 4a, the Beta factor cannot be eliminated by a judicious choice of circuit components.


See circuit diagrams above. For a p-channel JFET, all the voltage polarities in the network are reversed as compared to an n-channel device. The data obtained in this experiment was based on the use of a 10 volt Zener diode. Events repeat themselves after this. This is probably the largest deviation to be tolerated.

The threshold voltage of 0. As the temperature across a citcuitos increases, so does the current. R and C in parallel: With potentiometer set at top: Z1 forward-biased at 0. Since log scales are present, the differentials must be as small as possible.

It is essentially the reverse saturation leakage current of the diode, comprised mainly of minority carriers. The enhancement MOSFET does not have a channel established by the doping sequence but relies on the gate-to-source voltage to create a channel. V1 12 V Also observe that the two stages of the Class B amplifier shown in Figure The output terminal QA represents the most significant digit.

Logic States versus Corcuitos Levels b.
