Hybrid Parameters are the values which is used to find FREQUENCY RESPONSE of a low frequency transistors. you may have doubt like why we are using only H-PARAMETERS why not HYBRID-PI models because..., h-parameters values are constant at low frequency moreover, at low frequency transition model we have assumed that the response of transistor to changes of input current or input voltage is instantaneous this is the reason why we had neglected shunt capacitances . as there were no shunt capacitances there is no chance of using hybrid-pi model. i hope you got answer for your question
Type your answer here... TO DECREASE THE COMPLEXITY . ANSWER: h parameters are used to analyze small signal behavior o a transistor.
In transistors, current gain plays a significant role. In h parameters, one of the parameters is hfe which is current gain. It is easier if the parameters chosen represent some significant properties of the device. Some other parameters of importance in transistors are input resistance hie and output resistance 1/hoe.So it makes sense to analyse transistors with h parameters.
h-parameters are Real Numbers up to radio frequencyThey are easy to measureThey can be determined from transistor static characteristic curvesThey are convenient to use in circuit analysis and designEasily convertible from one configuration to otherReadily supplied by manufacturers
Answerthe h parameter or the hybrid parameters of a transistor helps us to analyse the amplifying action of transistor for small signal .it is necessary for practical purposes.In generally there are four type of h parameter.these are :h11h12h21h22
hf
r parameter is resistance parameter
In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.
At different parameters the input and output relation differs ,amplification factor varies across the various configuration of transistor. To know how to use the transistor weather as a switch or as an amplifiers analyzing it across all the parameters is important.
R. Paul has written: 'Measurement of transistor parameters'
These are the parameters which are used(mainly by the manufacturers) to specify the characteristics of a transistor. They hav bcome so popular bcoz. they r easily measurable
Use of h - parameters to describe a transistor have the following advantages. 1. h - parameters are real numbers up to radio frequencies . 2. They are easy to measure 3. They can be determined from the transistor static characteristics curves. 4. They are convenient to use in circuit analysis and design. 5. Easily convert able from one configuration to other.
ALL transistors can be used as switch. however there are certain parameters to be noted. speed saturation and storage time. Once a transistor is saturated current may flow either way
FET is abbreviation of Field Effect Transistor. This is a transistor in which current is controlled by voltage only and no current is drawn. It is a high input impedence device and is used in computers, telecommunication and control circuits. This transistor is better in certain parameters as compared to BJT, that is Bipolar Junction Transistor.
Bias instability in sensors can be caused by temperature changes, mechanical stress, aging of components, and external magnetic fields. These factors can impact the sensor's internal structure, affecting its ability to maintain a stable bias output over time. Calibrating the sensor periodically can help compensate for bias instability.
