Depending on the other components in the circuit this modulated current flow can be used to provide current or voltage gain.
12.
Therefore, the voltage gain Ar of the secondary coil with respect to the primary coil when the system is resonating,
13.
The Ferranti effect describes the voltage gain towards the remote end of a very lightly loaded ( or open ended ) transmission line.
14.
If the output of the Wilson mirror is connected to a relatively high impedance node, the voltage gain of the mirror may be high.
15.
A more complicated analysis of the common-base oscillator reveals that a low frequency amplifier voltage gain must be at least four to achieve oscillation.
16.
Vacuum-tube tetrodes, using a screen grid, exhibit much lower grid-plate capacitance and much higher output impedance and voltage gains than triode vacuum tubes.
17.
If the second stage has an effective input capacitance C and voltage gain A _ { 2 }, then slew rate in this example can be expressed as:
18.
In the typical 741 op amp, the common-mode rejection ratio is 90 dB, implying an open-loop common-mode voltage gain of about 6.
19.
If an amplifier has a gain bandwidth product of 100 MHz, then it would have a voltage gain of 100 at 1 MHz but only 10 at 10 MHz.
20.
In most cases, the electronics in the microphone itself contribute no voltage gain as the voltage differential is quite significant, up to several volts for high sound levels.
