## PSPICE time and voltage dependant parts and circuits

Implementing an analog behavior model with TIME variable dependency means to include an independent source to the model. Although the option is provided by the pspice abm syntax, it's not genuine behavior modeling. I didn't yet experience a simulation case where a similar combination seemed useful. If there's a time dependency to be modeled, it can

## sigma delta design problem

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

## mathematical equations of brushless dc motor in pspice

hi any body can help me to know about the equations of brushless dc motor i want to model it in pspice with abm please help me i'm in urgent

## Which S/w can simulate piece-wise time varying capacitance ?

You didn't specify the problem clearly. Nonlinear (e.g. voltage dependant) is different from time varying. Nonlinearity is provided in pspice by a linear and quadratic voltage coefficient. Piecewise linear would need your own implementantion. It can be found e.g. in power MOSFET models, see below example of a nonlinear Csd capacitance (copied fr

## VCVS output value has to bring as the resistance element value in pspice ABM model

Use the ZX subcircuit from the MISC.LIB (s. the MicroSIM pspice Application Notes, pp. 159-160).

## About designing an op-amp circuit where Vout will be the root of input voltage.

In pspice, a square root circuit can be easily "designed" by using abm (analog behaviour modelling). For a real hardware circuit, you can refer to analog multipliers, see an example in the AD633 datasheet Or use a suitable combination of log/antilog circuits. The basic conce

## Power Device PSPICE Macromodel Convergence Problem

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

## Difficulty in putting transconductance value in ideal VCCS 'G' in PSPICE.

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.

## Inserting dependent sources in PSPICE

2nd Tutorial on pspice

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)?

## Question regarding Laplace and Op-Amp

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?
