The higher the peak value of the gate current the sooner the triggering level will be reached and conduction initiated. The vertical circuitoe of the waveform was equal to the battery voltage. For the positive region of vi: VT Vdc 2V Design parameter Measured value AV min. See Circuit diagram 9.

The most critical values for proper operation of this design is the voltage VCEQ measured at 7. Common-Base DC Bias a.

V IN increases linearly from 6 V to 16 V in 0. The LCD depends on ambient light to utilize the change in either reflectivity or transmissivity caused by the application of an electric voltage. In close agreement 3. The output impedances again are in reasonable agreement, differing by no more than 9 percent from each other. The J and CLR terminals of both flip flops are kept at 5 volts during the experiment.

For voltage divider-bias-line electronicis Fig. See probe plot page Boylesta also, that as the output voltage approaches its maximum value that the efficiency of the device approaches its theoretical efficiency of about 78 percent. Both input terminals are held at 5 volts during the experiment. Collector Feedback Configuration with RE a.

This is a logical inversion of the OR gate. Beta did increase with increasing levels of VCE. The drain characteristics of a JFET transistor are a plot of the output current versus input voltage.

Numeric Logarithmic fC low: Remember me on this computer. For the BJT transistor increasing levels of input current result in increasing levels of output current. Its amplitude is 7.

Waveforms agree within 6. The frequency of 10 Hz of the TTL pulse is identical to that of the simulation pulse.

Slight variance due to PSpice cursor position. Low Frequency Response Measurements b. Emitter-Follower Flectronicos Bias a. The effect was a reduction in the dc level of the output voltage. See tabulation in 9. The resulting curve should be quite close to that plotted above.

Thus, the design is relatively stable in regard to any Beta variation.

It is essentially the reverse saturation leakage current of the diode, comprised teoia of minority carriers. The maximum level of I Rs will in turn determine the maximum permissible level of Vi.

Theoretically, the most stable of the two collector feedback circuits should be the one with a finite RE.

Again, depending on how good the design of the voltage divider bias circuit is, the changes in the circuit voltages and currents should be kept to a minimum.

For germanium it is a 6. Series Voltage Regulator a.

For more complex waveforms, the nod goes to the oscilloscope. For forward bias, the positive potential is applied to the p-type material and the negative potential to the n-type material. This represents a 1. Problems and Exercises 1. Either the JFET is defective or an improper circuit connection was made.

There is one clock pulse to the left of the cursor. The IS level of the germanium diode is approximately times as large as that of the silicon diode. The difference between the input voltages and the output voltage is caused by the voltage drop through the flip flop.

The difference in the experimentally determined propagation delay was 13 nanoseconds compared to a propagation delay of 12 nanoseconds as obtained from the simulation data.

Low-Pass Active Filter a.
