lm385 in orcad seeking another

[deepu7]

please some one tell me why am getting the error to connect more than one connection at the transistors emitter and at LM385 as in the fig.

the following is the error generated

.INC "..\SCHEMATIC1.net"

Check your net connections ....it appers that net is not connected porperly.....delet the net which shows this problem and try to redo the net connection again.... this is standard ERC error that you are getting

Good Luck

i have Lm385,Lm385-1.2,LM385-2.5 in the ORCAD library
so as to construct the circuit in fig attached pls suggest which component model can be used

 

[atripathi]

you should try the LM385 from opamp.olb from ../tools/capture/library/pspice folder. It seems that you have used this part from an library under ../tools/capture/library
This should also fix the Less than 2 connections issue

 

[deepu7]

its not a opamp its a micropower 3-terminal adjustable band-gap voltage reference diode and am not supposed to use a opamp

in the link u can see what i really want

in page9 there is a current source circuit and i want to simulate it pls give me the library location of lm385 to be used if possible any ckt even

**broken link removed**

 

[atripathi]

I know, In's an 3 terminal regulator, you will find this part/model in mentioned opamp.olb under ../tools/capture/library/pspice/opamp.olb. You may want to try that first.

sorry to say this again am getting the below result when i did as u said

from which library you have placed the two BJTs? They appears to be from one of the library under ../tools/capture/library. These symbols do not have associated PSpice simulation model and hence they do not appear in PSpice netlist. For PSpice simulation always use the library/symbols from ../tools/capture/library/pspice folders.

Hope this helps.
