How does a jfet input operational amplifier work?
A: an operational amplifier has two input A+ and a - input feeding to a base of a transistor ideally both diodes are matched with a current source to make them equal so basically they are both balanced or virtually at the same potential increasing one potential to one will inversely effect the other. usually these junctions are transistor base to emitter but it could that one is just a plain diode working on the exponential curve of the diodes
What is the voltage gain of the 2n2222 amplifier?
A: The gain of a transistor is not linear and even that varies from component to component. The gain can vary greatly depending on the Ic current and the load. Manufactures only give out a typical gain for a particular current. As a rule the lower the Ic current the higher the gain. To really find out what a particular transistor characteristics are a tektronik curve tracer is used.
In what region of their characteristic curve are zener diodes operated?
Zener diodes are normally operated in their reverse breakdown voltage curve.
What is Analog multiplier using emitter coupled transistor pair?
The standard analog multiplier circuit (i.e. multiplying two analog signals to generate a product analog signal) sums the logs of the inputs then takes the antilog to form the output. The log and antilog functions are approximated using the base-emitter curve of transistors. The rest of the circuit is opamps, which have emitter coupled differential transistor amplifiers at their core. This however is limited to positive values only, and is called a one quadrant multiplier. Perhaps you are asking instead about a type of analog multiplier using two cross-connected emitter coupled differential transistor amplifiers and several constant current sources for bias. The main advantages of these is they can correctly handle negative numbers, and are thus called four quadrant multipliers, and they are almost trivial to integrate compared to the opamp version.
Viva questions on analog electronics lab 3rd semester engineering?
For example , if you are conducting the RC coupled the amplifier, the will be frequency response curve , due to which cc ,cce and ccb of internal capacitance of the transistor , In that you have take the gain as 3db .. at frequency response ,they will ask why you have to select the #db.. instead of 3db you select $ or 6db's .. I will tell the reason later !!! Bye
What is the purpose of determining frequency response?
frequency response curve helps us to find the bandwidth of particular amplifier circuit. Bandwidth is the range of frequency at which the amplifier works better....
Definition of half-power frequency?
The frequency on an amplifier response curve which is greater than the frequency for peak response and at which the output voltage is 1/√2 (that is, 0.707) of its midband or other reference value.
What is a resonance curve?
A resonance curve is a graph that shows the relationship between the amplitude of a system's response and the frequency of an applied periodic force. It typically exhibits a peak at the system's resonant frequency, which is when the system's response is maximized. Resonance curves are commonly used in physics and engineering to analyze the behavior of oscillating systems.
What is Frequency curve?
A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.
What is the scientific meaning of the phrase 'frequency response'?
Frequency response refers to how a system or device reacts to different frequencies of an input signal. It describes the relationship between the input frequency and the output amplitude or phase of a system, such as an electronic circuit or an audio device. A frequency response plot shows how the system attenuates or amplifies different frequencies.
How is a frequency curve in statistics different from a frequency polygon?
In order to plot the points on either the frequency polygon or curve, the mid values of the class intervals of the distribution are calculated. Then the frequencies with respect to the mid points are plotted. However in a frequency curve the points are joined by a smooth curve, where as in a frequency polygon the points are joined by straight lines. Apart from this major difference, a frequency polygon is a closed figure where as the frequency curve is not.
What is cumolative frequency curve?
A cumulative frequency curve is a graph that shows the cumulative frequency of a data set. This type of graph can present data, such as medians and quartiles. Another name for this curve is an Ogive.
Dc and ac analysis of Differential amplifier?
DC Analysis: For this analysis, frequency is made zero and the voltage of the source is increased in small steps from 0V.And the output voltage is plotted. So, finally we get a Vout vs Vin curve. AC Analysis: In this analysis, we choose an AC source. We keep the Offset voltage = 0V, AC voltage or small signal voltage = 2V (You can take any voltage you wish and it doesnt matter). So, to plot the ac response or frequency response of the circuit, increase the frequency in steps and note the output voltage. from this analysis , we can find the gain of the circuit over frequency.
What is meant by a frequency response curve of an acceptor circuit?
A frequency response curve of an acceptor circuit illustrates how the circuit's output amplitude varies with different input frequencies. It typically shows the gain or attenuation of the circuit across a range of frequencies, highlighting its behavior at resonance and in the passband. This curve helps in understanding the circuit's performance, including bandwidth, cutoff frequencies, and how effectively it accepts or rejects signals at various frequencies. Overall, it is a crucial tool for assessing the circuit's filtering characteristics.
What is gaussian frequency curve?
The Gaussian curve is the Normal distributoin curve, the commonest (and most studied) of statistical distributions.

How can one determine the concentration of a sample using a calibration curve?
To determine the concentration of a sample using a calibration curve, you first need to measure the response of known standard samples with known concentrations. Then, plot a calibration curve by graphing the response against the concentration. Finally, measure the response of the unknown sample and use the calibration curve to determine its concentration by finding where its response falls on the curve.
