Miller effect

[′mil·ər i‚fekt]
(electronics)
The increase in the effective grid-cathode capacitance of a vacuum tube due to the charge induced electrostatically on the grid by the anode through the grid-anode capacitance.

At the low-end-torque with an engine speed of 1250 rpm, the occurrence of knocking despite the Miller effect and strongly retarded combustion limited further increase of the load above 21 bar IMEP.
At part load operation, despite the lower effective CR, advantages regarding ISFC are present with the Miller camshaft at engine speeds below 3000 rpm due to the pronounced Miller effect.
Apart from engine speeds below 2000 rpm, where the Miller effect is very pronounced, the knock limited loads are very similar for both engine configurations.
The Tempus Timing Signoff Solution is a silicon-accurate, color-aware timing signoff and signal integrity analysis tool that supports advanced-node design requirements for waveform propagation, Miller Effect, ultra-low power, and variation associated with multi-patterning technologies.
Liverpool were first to feel the Miller effect as the Blues danger man tore into the Reds with purposeful endeavour.
This deep diffusion causes the Miller effect capacitance (shown in blue) to increase, which is deadly at high frequencies, since it acts as a negative feedback, reducing gain and circuit stability.
The HV100/HV101 provide Supertex's patent-pending short-circuit protection that looks for the Miller effect rather than relying on an external sense resistor.
The circuit is noninverting and the collector of Q1 is AC grounded, thus eliminating the Miller effect at the base of Q1.
