Usually, however, technology only permits a close replica of the desired characteristics. Circuit operates as a window detector.
High Frequency Response Calculations a. Since the stability figures of both of those circuits are so small, the apparent greater stability of the collector feedback circuit without RE is probably the result of measurement variability.

The experimental and the simulation transition states occur at the same times. The output of the gate, U1A: Hence, so did RC and RE.
See above circuit diagrams. The voltage-divider bias configuration was the least sensitive to variations in Beta.
The levels are higher for hfe but note that VCE is higher also. For germanium it is a 6. LED-Zener diode combination b. Voltage-divider Circuit Design a. Either the JFET is defective or an improper circuit connection was made. 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.
The logic states of the simulation and those experimentally determined are identical. The higher the peak value of the gate current the sooner the triggering level will be reached and conduction initiated.

V1 12 V Therefore V C decreases. To shift the Q point in either direction, it is easiest to adjust the bias voltage VG to bring the circuit parameters within an acceptable range of the circuit design.
This is counter to expectations. See tabulation in 9. Draw a straight line through the two points located above, as shown below. The output terminal QA represents the most significant digit.
Both capacitances are present in both the reverse- and forward-bias directions, but the transition capacitance is the dominant effect for reverse-biased diodes and the diffusion capacitance is the dominant effect for forward-biased conditions.
A bipolar transistor utilizes holes and electrons in the injection or charge flow process, while unipolar devices utilize either electrons or holes, but not both, in the charge flow process. The slope is a constant value. There is almost complete agreement between the two sets of measurements.
VCsat and VP define the region of nonlinearity for each device.
Curves are essentially the same with new scales as shown. Low Frequency Response Measurements b.
Thus in our case, the geometric averages would be: Clrcuitos the BJT transistor increasing levels of input current result in increasing levels of output current. Note that no biasing resistors are needed for stage 2. Build and Test CE Circuit b. The measured values of the previous part show that the circuit design is relatively independent of Beta.
Common-Emitter DC Bias b.
For the positive region of vi:
