What is Miller Capacitance in a MOSFET?
and how do you calculate it from a typical MOSFET datasheet???
 

Miller Capacitance

Usually Cgd (or Cu) is the parasitic miller cap. as it is across an inverting gain stage (namely the MOSFET)
 

Re: Miller Capacitance

There is simple picture for you
 

Re: Miller Capacitance

Miller is the name of a scietnist. the miller capacitor is very useful for amplifier reference compensation.
 

Re: Miller Capacitance

Do a web search on Google for "What is Miller Capacitance in MOSFETs" ..

Miller Capacitance is usually given as Cgd capacitance versus Drain to Source Voltage .. see example below ..

Re: Miller Capacitance

AS far as I know, when your MOS is an amplifier, the capacitor get's multiplied by the gain (in a CS) and is reflected back. the caps are all parasitic
