Miller effect in mosfet
WebMOSFET – is an acronym for Metal Oxide Semiconductor Field Effect Transistor and it is the key component in high frequency, high efficiency switching applications across the electronics industry. It might be surprising, but FET technology was invented in 1930, some 20 years before the bipolar transistor.

In addition to the MOSFET switching behaviors and tradeoffs discussed above, fast switching can cause another appearance of the known Miller effect, which must be considered in a design. The Miller effect can lead to an induced V GS bounce caused by a gate inrush current, according to: baruk 142Web29 aug. 2013 · The key takeaway about the Miller effect is that it is due to GAIN across a gate-drain junction (or base-collector). So to reduce Miller effect you have to reduce the gain across that device? How do you reduce the gain across an individual device but maintain the same gain in the overall amplifier? You use a cascode transistor. baruka 50 ec
