    switching circuit simulation in hspice

    do you have idea of HSPICE RF version? As i dont have access to CADENCE .

    switching circuit simulation in hspice

    I am simulating a duty cycle resistor based neural amplifier . Duty cycle resistor basically have one switch of MOS and large resistor in kilo ohms. When the same circuit is simulated using simple resistor in place of duty cycle resistor then all results are fine for both AC analysis and trans...

    Width of FINFET

    can you elaborate more how to write code in hspice for FINFET..as i am unable to change the width ... M1 D S G1 G2 B pfet w=15u l=12n nfin =1 is this fine?

    Width of FINFET

    what if we want to decrease the width as number of fin cannot be reduced below 1 and also nfin must be integer

    Width of FINFET

    how to change the width of FINFET . I have designed an FINFET based differential amplifier using gm id technique and if i am using minimum fin number which is 1 then also my channel length goes in um range. Is there anyway to quantize the channel width

    plot gm id in hspice

    Hello all. I want to design my amplifier using gm/id technique in HSPICE. Now i have plot gm/id w.r.t to Vgs and also Id w.r.t to Vgs. One question is how can i plot gm/id w.r.t to Id if they both already have been plotted using DC sweep w.r.t to Vgs. Another question is how to plot Id/W/l ?

    HB NOISE Analysis

    I am working on hspice to run chopper stabilized amplifier for biomedical circuits. By using .NOISE command i am not getting accurate analysis of input referred noise PSD so i tried for .HBNOISE analysis. Stimulated result is showing in list file but i am unable to plot frequency plot of noise...

    FINFET BASED DIFFERENTIAL AMPLIFIER

    can you help how to apply differential voltage in this case?I found only way to apply differential voltage the one i have write in netlist

    FINFET BASED DIFFERENTIAL AMPLIFIER

    When i am stimulating same circuit without feedback bias difference is 0.Might be feedback is adding some error.

    FINFET BASED DIFFERENTIAL AMPLIFIER

    I havent done it intentionally.Can you please tell me more how to be sure that applied feedback is negative or positive?

    FINFET BASED DIFFERENTIAL AMPLIFIER

    You can check the netlist.i have given both common mode and sinusoidal signal Vd. I just want to check my amplifier works as gain amplifier by giving feedback resistor R1 and R2 and checking dc gain which is not even close to R1/R2.How to sort out this issue?
