Re: most mosfet can work on 1MHz

fumac said:
most mosfet can work on 1MHz perfect
u can read the datasheet, most of them were tested on 1Mhz
the correct type that i'm using ,i can't tell u:) sorry for that.

the hi-freq pwm,not just depend on fets,
the hold sch, the design of pcb,the return,etc..

a tips: look at class-d amp as a nomal amp...

i'll post the pic of freq-respont , plus-res, osc,etc..
perhaps,the pic of pcb

it is a hard work , because i'm not a full menber:)

IVX Seems it's a really nice technique to avoid royalty, just take up switching -BINGO!

hi ivx
not just take up the switching,
but it's a right way(phps not just i think)



classd_fromru
frequency is not important, patented only RC elements in feedback
====
i dont think so
the feedback not just for freq

Helou, IVX, my respect. Didn't see you on vegalab for a long time.

Fumac, philips patented principle, but you talk only about switcing freq...it's not correctly.

Maybe if you tell us little more about your shematics and difference, all question will be closed.


ps: this thread like Bryton in USA..
