How to match negative Zs with Smith Chart? ( -28.526393888 + 70.854968742i)
I am using Smith v3.10. After calculating required Zs for transistor matching, i realized that Re part is -28, and can't be put into program.
How to solve this problem? Samples from my book have no such case.
Sure it can have a negative real part, if it's an active network. But you can't match to it with a lossless network. You can either move Z into the RHP using series/shunt resistance, or change the transistor circuit to give a RHP Z.
