Hello to All.
i need to simulate current source according to timing diagram.
how can i do it in pspice modeling in Orcad???
how do i built this model??
need i two current sources??
thanx.
timing diagram:
Yes. You can put a switch in series to break a voltage but if you put it in series with an ideal current source, the current will still manage to get through the switch even if it is 1G ohm. You just need to dump the current somewhere i.e. Short it out.
I cannot see all the switch parameters. There is usually an on and off resistance. The defaults might be 1 ohm and 1 meg ohm. You need to change those, particularly the 1Meg.
I cannot see the simulation very well on my phone but you need to consider the effect of some current going through the switch resistance. That is why you need to increase the off resistance - a lot more than 1Meg.
