How mosfets work

WebPower MOSFETs have a different structure from the lateral MOSFET: as with most power devices, their structure is vertical and not planar. In a planar structure, the current and breakdown voltage ratings are both functions of the channel dimensions (respectively width and length of the channel), resulting in inefficient use of the "silicon real estate". Web20 dec. 2024 · They function by quickly switching to and fro amongst the supply rails, being provided by a modulator using pulse width, pulse density, or related methods to encode the sound input into a pulse train. The sound gets through via a easy low-pass filter into the loudspeaker. The high-frequency pulses are blocked.
