When the forward saturation in Bipolar junction transistor occurs?
Forward saturation in a BJT occurs when the ratio of collecter-emitter current and base-emitter current reaches hFe or dc beta. A that point, the BJT is no longer operating in linear mode.
Why fet is preferred over the bjt?
Disadvantage:Easy to damage when compared to BJT
What is the expected amplification of a bjt transistor amplifire if the dc supply is set zerovolts?
A: In mathematics it is learned that any part,number, items,are equal to zero if mulitplied by zero
Which quantity does a transister amplify?
Depends on the circuit the transistor is used in:it can amplify voltageit can amplify currentit can amplify power
Why the common mode signal should be rejected in differential amplifier?
because of the coupling between the two transister and absence of capacitance it can amplify both dc and ac
DC amplifier amplifies what?
A: Amplify DC a1 volt can be amplify to 10volts for example if need be
What is difference between ac and DC amplifier?
AC amplifiers are used to amplify AC signals and use components that handle large voltage values. DC amplifiers are used to amplify DC signals which use small powered electronic devices.
What type of signal to amplify by using differential amplifier?
ac and dc
What is the expected amplification of a BJT transistor amplifier if the dc supply is set zero volts?
very simple, zero.
How does frequency affect amplitude?
we use dc supply for amplifcation and dc have no frequincy. we amplify just signal curent or signal voltage.
Ac and dc load line of BJT-explain?
when the dc supply given, dc load line lies in the Ic and Vcc. when the AC supply given, AC load line lies in the Ic and Vcc.
When the forward saturation in Bipolar junction transistor occurs?
Forward saturation in a BJT occurs when the ratio of collecter-emitter current and base-emitter current reaches hFe or dc beta. A that point, the BJT is no longer operating in linear mode.
What 3 things does an electrical amplifier amplify?
An electrical amplifier amplifies 2 physical quantities according to the transistors used. If a BJT is used it amplifies the current and if a MOSFET is used it amplifies the voltage. Hybrid amplifiers amplify current as well as voltage so in theory , current voltage and power is amplified.
What is the code that you have to write in simulation programm hspice to take a current-voltage characteristic curve of a bjt transistor?
we will perform a dc analysis over it
Why do you supply DC power?
DC power supply is used to power the IC's and other active and passive devices.It is provide to amplify the weak signal with the help of amplifiers.
Why bjt is bipolar?
Bjt is bipolar because in bjt the conduction of current is due to the electrons as well as holes
Why fet is preferred over the bjt?
Disadvantage:Easy to damage when compared to BJT
