Hi, all:function SetDomain(d) { document.domain = d; } Did hspice included the variation of gm (CMOS) over broad frequency upto 20G ? Since it takes electrons finite time to pass through the channel, so there will be a up-limit frequency which eletron will forever stay in the channel. Did hspice take that into account? In another way, if no parasitic capacitance exists, will the cut-off frequency of mosfet in hspice simulation be infinite ? (The reason I did not do the test it myself is that it looks that impossible to remove all cap in the process file, maybe some avanti guies can answer this problem.) --------------------------------- Do You Yahoo!?
