So you mean the inductance introduced by bondwire doesn't change the performance of on-chip device since on-chip device has it's own on-chip ground , could I understand in this way? But we usually say that in high frequency,the bondwire inductance could not be neglect...
In my view, lambda/4 line is actually connected to ground through bondwire inductor which has very high-impedance over 70GHz,so what the other end of the line see is not high impedance but very low impedance,and it completely changes my intention...
I'm looking forward to your kind reply
