re：HF rectifier simulation

Hello everyone,

I'm trying to simulate a HF rectifier circuit but from the results the diodes are not simulated correctly (i.e. as diodes) and as the circuit is a voltage quadruple rectifier the output should be more than 63mVpp which is simulated on the input. I feel that the diode rectifying function is not correctly simulated. Please advise
PS: I also ran a power test for an input power of -20dBm ( as for amplifiers) and i get a o/p power of -19dBm-makes no sense
Thank You Ed

I'm assuming you are expecting the AC signal to be rectified. AC simulation does not work this way. It linearizes the circuit around the DC operating point and then just computes small-signal results. I recommend you try using harmonic balance instead.
