Hi all,
i am trying to design a sigma delta modulator in **pspice** by **abm** library , here it is my schematic , nut it dont work!
first block subtract the input from output , then the result goes to integrator and then if the result is positive the output becomes 5 , else the output becomes zero and this output goes to 74175 that its clock rate is 10k

i want to model it in **pspice** with **abm**
please help me i'm in urgent

Thanks for the reply
Im a newbie to **pspice**. Will the time varying capacitors will already be available in **pspice** ? If possible can u please specify how to approachf
Thank you

Hi,
I've been working on a power device macromodel based on **abm**, but I got stuck in convergence issues (transient analysis) when Vdd goes over 100V
I changed RELTOL, ABSTOL, VNTOL, etc., but I wasn't yet able to have it working with higher voltages.
The model is in the attached pdf. I am using **pspice** from Cadence SPB v16.3
Any ideas?
T

It is still showing transconductance of 1S
Looks like. But it's surely not a general **pspice** problem. You may want to inspect the generated netlist. Or post the project files.

Hello all,
İ want to plot my bandpass filter's transfer fucntion which is in s-domain.For example i have Vo/Vi=(0.03s/s^2+3s+5) how can i plot it in orcad **pspice**(v16.3)?

Hi guys,
Right now I've a Laplace **abm**-Filter(PI Filter) in my **pspice** Simulation. I want to replace the Laplace **abm**-Filter with a real OP-Amp. My question is, will the Vcc+ and Vcc- of the Op-Amp influence my result?

I want to circuit modeling rate equation using **pspice**.
For example :
c1*dv1/dt = v1/a - v2/b + c*v1*v2
that each term refer to a current and v1 and v2 refer as node voltage.
c1*dv1/dt ====> current of a capacitor
v1/a====> current of a resistor
v2/a====> current of a resistor
and my question:
how can I model the last term?
can we use a VC

Hi!
When I simulate power electronic circuits in **pspice** I got large *.dat file as a result (<=2GB). Circuit is very big with **abm**, digital and analog parts and with large values of voltage, current and requency.
Is there any way how can I change deafult max value for this in **pspice** which is 2GB (I need bigger) or how can I change some (...)
