Since all the system terminals are at 10 V the required difference of 0. Positive half-cycle of vi: Positive pulse of vi: Negative pulse of vi: However, vo is connected directly through the 2. For the positive region of vi: The right Si diode is reverse-biased. For the negative region of vi: The left Si diode is reverse-biased.

Using the ideal diode Using the ideal diode approximation the vertical shift of part a would be V rather approximation would certainly be appropriate in this case.

Solution is network of Fig. Network of Fig. The maximum level of I Rs will in turn determine the maximum permissible level of Vi. Z1 forward-biased at 0. 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.

Forward- and reverse-biased. The leakage current ICO is the minority carrier current in the collector. The separation between IB curves is the greatest in this region. In active region.

Output characteristics: Curves are essentially the same with new scales as shown. Input characteristics: Common-emitter input characteristics may be used directly for common-collector calculations.

The levels are higher for hfe but note that VCE is higher also. As the reverse-bias potential increases in magnitude the input capacitance Cibo decreases Fig. Approximation approach: Exact analysis: Network redrawn to determine the Thevenin equivalent: For current mirror: If operating properly: For the emitter-bias: For collector-feedback bias: Considerably less for the voltage-divider configuration compared to the other three. S VBE: The voltage-divider configuration is the least sensitive with the fixed-bias similar levels of sensitivity.

In general, the voltage-divider configuration is the least sensitive with the fixed-bias the most sensitive. For the voltage-divider configuration the opposite occurs with a high sensitivity to In total the voltage-divider configuration is considerably more stable than the fixed-bias configuration. Using the exact approach: For each stage: From problem Log-log scale! The collector characteristics of a BJT transistor are a plot of output current versus the output voltage for different levels of input current.

The drain characteristics of a JFET transistor are a plot of the output current versus input voltage. For the BJT transistor increasing levels of input current result in increasing levels of output current. For JFETs, increasing magnitudes of input voltage result in lower levels of output current.

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. VCsat and VP define the region of nonlinearity for each device.

For a p-channel JFET, all the voltage polarities in the network are reversed as compared to an n-channel device. In addition, the drain current has reversed direction.

From Fig 6. In the depletion MOSFET the channel is established by the doping process and exists with no gate-to-source voltage applied.

As the gate-to-source voltage increases in magnitude the channel decreases in size until pinch-off occurs. 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.

The larger the magnitude of the applied gate-to-source voltage, the larger the available channel. From problem 14 b: Network redrawn: Either the JFET is defective or an improper circuit connection was made.

Possible short-circuit from D-S. Draw a straight line through the two points located above, as shown below. Add 0. From 2N data: In fact, all levels of Av are divided by to obtain normalized plot. The resulting curve should be quite close to that plotted above.

Use an expected shape for the curve noting that the greatest From problem 2: Circuit operates as a window detector. See section With potentiometer set at top: For current loop: A line or lines onto which data bits are connected. Open-collector is active-LOW only. DC bias: See Fig.

Note that the slope of the curves in the forward-biased region is about the same at different levels of diode current. Temperature on linear scale 6. High-power diodes have a higher forward voltage drop than low-current devices due to larger IR drops across the bulk and contact resistances of the diode. The higher voltage drops result in higher power dissipation levels for the diodes, which in turn may require the use of heat sinks to draw the heat away from the body of the structure.

At 1 MHz: The op-amp active filter provides controllable cutoff frequencies and controllable gain. The upper cutoff frequency and voltage gain are given by: High--Pass Filter High.

The cutoff frequency is determined by: Bandpass Filter There are two cutoff frequencies: They can be calculated using the same low-pass cutoff and high- pass cutoff frequency formulas in the appropriate sections. Flag for inappropriate content. Related titles.

Multiple--Stage Gains Multiple The total gain 3-stages is given by: Voltage Summing The output is the sum of individual signals times the gain: Current--Controlled Voltage Source Current This is simply another way of applying the op-amp operation.

Current--Controlled Current Source Current This circuit may appear more complicated than the others but it is really the same thing. Instrumentation Circuits Some examples of instrumentation circuits using op- amps: Instrumentation Amplifier For all Rs at the same value except Rp: High--Pass Filter High The cutoff frequency is determined by: Anupam Ojha.

Dragos Bacioiu.In fact, all levels of Av are divided by to obtain normalized plot. Voltage Summing.

Saiful Hasan Shujan. As noted in Fig. The resulting curve should be quite close to that plotted above. The transition capacitance is due to the depletion region acting like a dielectric in the reverse- bias region, while the diffusion capacitance is determined by the rate of charge injection into the region just outside the depletion boundaries of a forward-biased device.

At higher illumination levels, the change in VOC drops to nearly zero, while the current continues to rise linearly. Rights and Permissions Department. As the magnitude of the reverse-bias potential increases, the capacitance drops rapidly from a level of about 5 pF with no bias.

From Fig.
