    How can I extract samples of a sinusoidal wave in ELDO?

    ELDO Hi, How can I extract samples of a sinusoidal wave at regular time points in ELDO? Ex. a sample of a wave at t=1,2,3,4,5.... I tried .extract label=curve yval(<wave>,1n) And got one point, but how can I extract the other samples in the same simulation Christian

    How the effect of NBTI degrades Vt in a pmos transistor?

    NBTI on pmos Hi, Can anyone tell me how the effect of NBTI degrades Vt in a pmos transistor? Is this effect greatest the first few days/minutes, or will it degrade the transistor even more over the years? I have tried to simulate this in ELDO, but I don't know if the simulation is...

    Measuring the linearity of a switch

    I have simulated the on-resistance, but isn`t non-linearity caused by both on-resistance and junction capacitances? The dominating of them is determined by the output impedance of the source. I would like to get a plot of the harmonic distortion (2nd and 3rd harmonic) versus the output impedance...

    Measuring the linearity of a switch

    Hi, Has anyone got any tips on how to measure the linearity of a switch, without using a complete switchcap circuit. I need to compare the linearity of two bootstrapped switches. :) Christian

    ELDO reliability simulation

    Hi, The aging parameters came along with the designkit we are using. The designkit is 90nm from CMP, but the only library I found containing aging parameters were something called NBTI.lib. I suspect that the .age function doesnt get all the right parameters from this design kit. Christian

    ELDO reliability simulation

    Hi, Has anyone done simulations using the .age command in ELDO, to estimate the effect of NBTI on pmos transistors? I am trying to make this work, but the problem is that I get the same results wheter I simulate with an age of 1 year, 30 years, 100 years and so on... Does anybody know what...
