The problem is that SPICE will not be able to calculate the initial bias point - it has no stable bias point. Try BOTH telling it to skip that=20 calculation and put a very large value resistor in parallel with the cap (maybe 1000G o= hms) Best regards, =20 --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
