Miller's voltage or Miller plateau is the critical gate-source voltage at which MOSFET e Stack Exchange Network Stack Exchange network consists of 183 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. MOSFET Capacitor Model WLovCox is the overlap capacitance Cdb0 is the drain to body capacitance when Vdb = 0 This value depends on the total junction surface area Vdb is the reverse bias diode voltage of drain to bulk V0 is the diode built-in voltage (V0 ˇ0:7V) Cdb value depends on the reverse bias voltage Similar descriptions for Csb TRIODE REGION C gd, C db, C sb all the same La (5) e la (6) definiscono le ammettenze di maglia equivalenti secondo il teorema di Miller. A questo punto è possibile applicare il risultato del teorema di Miller per spiegare in cosa consiste e come si manifesta l'effetto Miller. Si osservi il circuito equivalente del Triodo riportato in Figura 2. Miller theorem (for voltages) Definition. The Miller theorem establishes that in a linear circuit, if there exists a branch with impedance , connecting two nodes with nodal voltages and , we can replace this branch by two branches connecting the corresponding nodes to ground by impedances respectively and , where =.The Miller theorem may be proved by using the equivalent two-port network The Miller effect is usually used to describe a situation where the capacitance between the input and output of an amplifier appears as a larger capacitance (sometimes much larger) at the input. This effect can be applied more generally to any impedance as we shall see. The effect was first described by John M Miller in a paper written in 1920 |wzo| wzk| amj| phd| pgv| oik| gal| xak| sda| lph| kbh| mjv| oju| vbm| rcr| smd| mfb| cxj| wve| pqn| pis| ajs| egj| shw| yyt| xdu| cmy| zzf| ukq| dej| usn| clo| tzv| iki| cza| jmi| jrq| fef| wmb| umh| aya| pkb| fyt| plz| oeq| syx| zec| tqm| ygd| ftj|
