Analyzing Rectifier input and output waveforms

Hi Guys,

I am simulating a cross- coupled rectifier and need help in analyzing the input and output rectifier waveforms for correcting the circuit.

Need Help!!

Thanks,:smile:

I don't understand your circuit. You have the signal going to the MOSFET gates but nowhere else. How do you expect a signal on the output?

Apologies for placing the incorrect snapshot. Here's the correct circuit for simulation connected to a cmut as a source. The snapshot cmut (capacitive micromachined ultrasonic transducer) is separately provided and modified in the post above. https://obrazki.elektroda.pl/6520519600_1363628171.png

So what do you expect to see and how does the simulation differ from that?

The output voltage waveforms should be that of an ideal full wave rectifier. But It is not so ( illustrated in the third snapshot) I need to analyse and correct the circuit specifications accordingly to receive the correct output waveforms

I added coupling capacitors and the output voltage is regulated now. However the PCE is very low. Could anyone suggest me an idea to increase the PCE?
