What is voltage shunt amplifier?
In Voltage Shunt Amplifier, the Output voltage is supplied in parallel with the Input voltage through the feedback network.
Why does amplifier gain reduce?
Since we know that the amplifier gain is given by A=Output voltage/input voltage (where A is the amplifier gain) So, it can be written as output voltage=A*input voltage, so when the output part increases gain increases but when input part increases gain decreases
What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
What is phase difference between input and output waveforms of ce amplifier?
180 degree phase shift
How do you calculate output offset voltage?
Output offset voltage is the output of an operational amplifier when the two inputs are shorted together (and often tied to ground). >> The output offset voltage (Voo) is caused by mismatching by two input terminals. Even though all the components are integrated on the same chip, it is not possible to have two transistors in the input differential amplifier stage with exactly the same characteristics. This means that the collector currents in these two transistors are not equal, which causes a differential output voltage from the first stage. The output of first stage is amplified by following stages and possibly aggravated by more mismatching between them. Thus the output voltage caused by mismatching between two input terminals is the output offset Voo .

How is slew rate affect on amplifier?
as it is rate of change of output voltage..so it affect amplifier output
What is the phase relationship between the input and output voltage of a common emitter amplifier?
In common emitter amplifier circuit, input and output voltage are out of phase. When input voltage is increased then ib is increased, ic also increases so voltage drop across Rc is increased. However, increase in voltage across RC is in opposite sense. So, the phase difference between the input and the output voltages is 180 degrees.
What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
What type of signal at the NPN output?
A: It always a voltage since it is a voltage amplifier
How do you use a diode as temperature sensor?
The voltage across a Silicon Diode junction varies 0.00011 volts per degree Kelvin. Connect the diode to a high gain amplifier and the output of the amplifier to a DVM using an appopriate voltage scale.
Why output voltage in common base amplifier is in phase to input voltage?
The output of a common emitter stage is inverted, it is not out of phase.
Amplifier voltage gain is 15db input signal is .8V what is output voltage?
54.6dB
How does the inverting amplifier differs from voltage follower circuit?
altough voltage follower circuit provides output voltage which is in phase to input voltage as in noninverting amplifier but in unamplified form.
What is the phase relationship between the input and output signals of the common collector amplifier?
Common emitter is the only transistor configuration that has an 180 degree phase difference between input and output. Common base and common collector outputs are in phase with the input.***********************************That is incorrect.The output of the common emitter is inverted, there is no phase shift.
Why you need operational transconductance amplifier?
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
