actually i want to shape the output current. so I do this:
where Id is a pulse in time and my_sine:

I now notice that the problem with this kind of implementation is that that my upper limit is...
where x is what? the simulation time?

my exponential curve is just the response curve to a final value which is depended on specific voltages which are given from a formula..

I would like to apply an exponential time delay to an current source that i model using verilog-a using Cadence.
I would like something like the transition operator but with emponential delay not a linear.
One more thing is that I want the on time delay to be different than the off...
Re: cadence ideal op amp
I have made this configuration, but when I design a voltage follower and put a pulse in the input I dont get anything in the output. Just a stable 0V signal. nothing changes. What's wrong?
I have "hspiceva" in the my license file but in my .lis file I get:

Hello i use HSPICE and want to use the opamp: LT6004. I have donwloaded the spice model from manufactures site (https://www.linear.com/pc/productDetail.jsp?navId=H0,C1,C1154,C1009,C1021,P29313) but i got the errors:
OPAMP as an integrator
It seems that i have find an cmos differential amplidier that will do the job.
Another question is, how will I set the values of the R and C to the Integrator to give me the exact integration to its output?
Added after 3 hours 39 minutes:
Nop the differential cannot...
OPAMP as an integrator
Hello is there any OPAMP that i can use as an integrator which can have low inpuit ranges? Even for 1uA??
I have used the OP-7c in HPSICE but it can handle currents only above 20mA..
Hello i was using the version 2003-03Sp1 without a problem. But i have instlled two newer versions : 2005-03 and 2007-3 and when i press to open the AvanWaves it crashes. The simulation is working fine. I have installed this versions to another computer and the wroking fine too. My computer is...
I am using 6.1 and when i try to use the polymeter i open and run :
For example i want to take measures of Voltage. I use from HM8112-3.llb the following in this order:
HM8112-3_Open_VISA_GPIB.vi , HM8112-3_Set_Function_Range.vi and then i open from
HM8112-3_DataRead.llb the HM8112-3_Read.vi...
