Sunny1,
While I am not experienced enough to offer advice on you ckt (I am waiting to see if my thinking is correct), I do have a question about your TINA output.
What do the little red marks at each junction mean? Do they mean no connection?
I have been trying out various simulators which include TINA. I am now down to LTspice (which is really shortcut driven), pSpice for TI and Multisim (which can be found Internet Archive).
The red marks are the connection handles for components. (The big black dots are only for junctions between traces.)
In school, we used both Tina and LTspice. (One teacher preferred one, the other teacher the other.) They both have their strengths and weaknesses. Setting up simulation parameters is much easier in TINA, and its schematic editor is less loony than LTspice’s*, but it has far fewer components to work with. TINA has an interactive digital logic simulator, which LTspice does not have at all, AFAICT.
*I find drawing a new schematic to be much faster in LTspice than TINA, but editing an existing schematic is much easier in TINA.
You managed to get pSpice working? I tried, but couldn’t make heads or tails of it…
