    Calculate PSRR of bandgap voltege reference by hspice

    excuse me can u write the command? i do not understand your means? I use this command in hspice: vdd vdd 0 dc=1.5 ac=1 .ac dec 10 1 20x .probe ac vdb(vref) but i cant get that result.

    ring counter at 0.35um process

    Hi all, I need a ring counter with 50 latch, that worked with clock @ frequency=4.3Ghz,i use c2mos latch but it can't work correct. one c2mos latch work correct at 4.3GHz but loop of 50th of c2mos latch didn't work.do u know any high speed latch??? i don't know why loop can't work.... the image...
