Electrical – How to make full wave rectifier


I observed one paper [A highly efficient interface circuit for ultra-low-voltage energy harvesting] and i tried Full-wave rectifier [attached in below].

enter image description here

But this circuit generating output wave form same as half-wave rectifier [observe in below].

I want to know this waveform is wrong or not?. Please, kindly consider my request and give me help.

You are using the wrong ground reference for your output voltage. You are measuring between GND and V+ instead of between V- and V+. When you do this you only get a half-wave output rather than a full wave.
