It is commonly used for small-signal devices in radio frequency applications where biasing the drain-side gate at constant potential reduces the gain loss caused by Miller effect, replacing two separate transistors in cascode configuration.
22.
That is why it is used to form emitter-coupled amplifiers ( avoiding Miller effect ), phase splitter circuits ( obtaining two inverse voltages ), ECL gates and switches ( avoiding transistor saturation ), etc.
23.
In that case the input impedance of the mirror may be affected by the Miller Effect because of \ scriptstyle C _ { \ mu 3 }, although the low input impedance of the mirror mitigates this effect.
24.
The tiny junction and stray capacitances between the base and collector terminals of a Darlington transistor, for example, may be drastically increased by the Miller effects due to its high gain, lowering the high frequency response of the device.
25.
Ordinarily these effects show up only at frequencies much higher than the roll-off due to the Miller capacitance, so the analysis presented here is adequate to determine the useful frequency range of an amplifier dominated by the Miller effect.
26.
Consequently, one way to minimize the Miller effect upon bandwidth is to use a low-impedance driver, for example, by interposing a voltage follower stage between the driver and the amplifier, which reduces the apparent driver impedance seen by the amplifier.

"' John Milton Miller "'( 22 June 1882 & ndash; 17 May 1962 ) was a noted American electrical engineer, best known for discovering the Miller effect and inventing fundamental circuits for quartz crystal oscillators ( Miller oscillators ).
28.
The switch-off time of your circuit drawn is prolonged by the Miller effect, see Common source # Bandwidth and the supply voltage must not exceed the transistor's V GSmax . talk ) 13 : 56, 27 June 2016 ( UTC)
29.
The Miller effect negatively affects the performance of the common source amplifier in the same way ( and has similar solutions ) . When an AC signal is applied to the transistor amplifier it causes the base voltage VB to fluctuate in value at the AC signal.
30.
These arrangements explain important circuit phenomena about modifying impedance ( Miller effect, virtual ground, bootstrapping, negative impedance, etc . ) and help in designing and understanding various commonplace circuits ( feedback amplifiers, resistive and time-dependent converters, negative impedance converters, etc . ).
