Amplifier voltage gain is 15db input signal is .8V what is output voltage?
54.6dB
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.
How does the non 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 voltage offset?
Input offset voltage is the equivalent voltage at the input of an operational amplifier. If an amplifier has a voltage gain of ten and an input offset voltage of 10 microvolts, a level of 100 microvolts will appear at the output with no input. Manufacturers try to design an op amp so the input offset voltage is as small as possible to minimize this error voltage at the output of the amplifier, especially for applications where small voltages are being amplified.
When transistor acts as an amplifier then does its output voltage increase or decrease?
That depends on both the input signal and the type of amplifier the transistor is used in.
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 voltage shunt amplifier?
In Voltage Shunt Amplifier, the Output voltage is supplied in parallel with the Input voltage through the feedback network.
What is invertion?
An inverting amplifier is one where the output is an inverted function of the input. The Class A transistor amplifier, also known as common-emitter, is inverting. As you increase the voltage on the base, the output voltage on the collector decreases. The operational amplifier has an inverting and a non-inverting input. In typical bridge mode, the output is inverted with respect to the (inverting) input, and the non-inverting input is used to reject common-mode input signals by moving the virtual ground point as needed.
What is non inverting amplifier?
The amplifier whose output is inphase with it input means if we consider voltage amplification then there is zero phase shift in input and 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 a common base NPN amplifier?
A common base NPN amplifier is used for high frequency applications as the base minimize oscillations at high frequency, separates the input and output. In a common base NPN amplifier the voltage gain is high, relatively low input impedance and high output impedance compared to the common collector.
Input resistance and output resistance of Voltage series feedback amplifier?
output resistance decreases and input resistance increases
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.
How does the non-inverting amplifier differ 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.
