I want to simulate a synchronous switched extraction circuit in pspice. Here the voltage across the capacitor controls opening and closing of the switch. How can I model switch in pspice.

I want to implement a digital controller for a switch mode power supply in Orcad pspice.
The controller will take voltages and current values as inputs and create the control signal using intelligent algorithms (state machines, digital control techniques etc).
Therefore I need a block that runs a code for processing these values (ie. C

switched-capacitor circuits can be simulated in the time domain (TRAN analysis) only, unless the S/C blocks are replaced by time-continuous equivalent blocks. Based on these linear replacements it is possible to display the frequency-dependent transfer characteristics (BODE plot).

It looks like V1 is set to switch every 3 seconds, but the output only shows 9 milliseconds.

I am new to use of Verilog-A programming. I had question regarding the use of this language.
I want to design the NEMS switch model using the Verilog-A model. Once I design this model will I be able to create a circuit simulation model of the NEMS switch which can be used as a model in pspice netlist to built larger (...)

I believe the non-infinity Roff of the switch causes the problem. Most simply, you'll check the "skip initial transient solution" option to overcome the problem.

Reconsider the switch parameters. My PMOS transistor model would have a negative threshold voltage, just for clarity
Flipping Ron and Roff doesn't seem to serve a reasonable purpose, except confusing yourself. It's all about specifying suitable Von and Voff numbers and connecting the switches correctly.

All your so called "transistors" (SPICE switch elements) have infinite bandwidth. You should add realistic node capacitance. Otherwise you can perform a purely digital simulation with less resource effort.

I don't know about floating nodes, but it won't like C3 - it will produce infinite current on switch on. You may as well remove it as it is across a battery with zero series resistance anyway, or add some series resistance to Vdc.
You are right, C3 is not necessary at all as it has zero ohms in parallel -

You can find switch in analog library. part names are S (Voltage control switch) and S_ST Voltage control switch with hysteresis effect. You can find some details about primitive devices in pspice reference guide.

Can someone help me with a lumped element model of a N-Channel Depletion Mode MOSFET? One that doesn't have the body diodes in it (being used as a switch).
If someone can post the schematic or a drawing it would be greatly appreciated.
I found this one and I guess I can just remove the diodes. I would be shorting the body to the source.

ha.. you have a difficult project ahead of you.
which version of pspice are you using?
the hard part will be how to deal with the floating grounds of your system. each "upper" switch in your bridge has its reference to the center node between teh 2 switches. you know what i mean?
each switch needs a gate (...)

But the switch which is suppose to turn on at 1V and off at 0v as its model suggests, does not switch and keeps giving a 0V at the output.

Change t=0 to whatever time you want the switch to open or close.
I think you may want to use an "E" which is a VCVS.

switch-Mode Power Supply Spice Cookbook covers it and includes a pspice model - it is included in smpsrecipes.lib and you can see the example netlist in for voltage mode.
I don't use pspice so I don't know if there are symbols made - if not, it's easy to make them.

I will try to help, but I am not sure it will be adequate:
You are using the MOST as a switch? If so, in which voltage does it operate? Did you tried transmission gate instead of single n-MOS or single p-MOS?
Have you placed dummy ( MOST connected as diodes) before and after the switch?
If you do the above, your switch will work (...)
