Hello everyone,
I am simulating a schottky diode power detector in ADS. The schematic and the diode model are in attachment.
I am interested in computing the extra DC current due to the RF input (due to the square term) to further compute its voltage sensitivity. Hence, I use Harmonic balance simulator to find the difference HB.I_Probe1.i[0]-DC.I_Probe1.i.
From the Taylor expansion of the diode IV equation, it can be found that the coefficient of the 2nd harmonic current term and the extra DC current is identical.
From the simulation, I can get HB.I_Probe1.i[2] to be close to the theoretical prediction but the DC term is very different.
Am I missing something?
