    [Merged]: Measuring Reverse Leakage Current

    If I understand it correctly, the subthreshold leakage current is the current flowing from source to drain. So I assumed that I can measure the leakage current from the current flowing from the drain. **broken link removed** I wanted to measure the leakage current in a single cycle where the...

    [Merged]: Measuring Reverse Leakage Current

    Reverse Leakage Current of a Rectifier I am trying to study the operation of this circuit, I am trying to measure the REVERSE LEAKAGE CURRENT of my main mos, but I don't really have any idea how. A friend of mine told me to use this testbench, The only problem is that her circuit is of...

    Power Conversion Efficiency?

    1. No, the input does not implement pfc 2. The AC input has a difference of 180 I will try to use this formula n= Pdc_output / S_input= Vdc*Idc/(2*Vrms*Irms) and see what happens...

    Power Conversion Efficiency?

    I have a problem with getting the power efficiency of my passive rectifier. I tried to use the formula found in this already closed thread: https://www.edaboard.com/threads/260495/ I used this formula =tperiod ∫((vplus(t)-|vminus(t)|)*(iplus(t)-|iminus(t)|)*dt) / tperiod t=0 I am confused...

    [Merged]: Measuring Reverse Leakage Current

    I have this circuit, it's actually a differential rectifier. How do I measure the reverse leakage current of my PMOS if my input is in AC? Is it possible to measure the leakage current directly on my circuit? Or do I have to characterize the MOS and use a testbench to measure the leakage...

    Power Conversion Efficiency of a Passive Rectifier?

    I do understand that Efficiency is Pout/Pin. My main concern is the input power, I don't really have an idea how to directly measure ac power at the source. So I ended up using this formula. t=tperiod ∫((vplus(t)-|vminus(t)|)*(iplus(t)-|iminus(t)|)*dt) / tperiod t=0 Transient of input voltage...

    Power Conversion Efficiency of a Passive Rectifier?

    I tried to use the formula found in this already closed thread: https://www.edaboard.com/threads/260495/ I am confused if it is applicable to my circuit. And does it apply to Output power too? I tried using same the formula but the result is much different from the expected output. Whenever...

    Power Conversion Efficiency of a Passive Rectifier?

    I have a problem with getting the power efficiency of my passive rectifier. It is mainly on the input side, how do you get an efficiency out of an RF input?

    RF-to-DC Rectifier Problem (SYNOPSYS Cdesigner)

    I also found out that PSIN and PORT are almost the same. Still I haven't figured out how to use this source type. Should I just continue using vsin? Is the 50 Ohm impedance already factored in in this source type?

    RF-to-DC Rectifier Problem (SYNOPSYS Cdesigner)

    We am currently working on a RF to DC rectifier design in cdesigner tool. We are having problem with our schematic mainly because I am confused with the source that we are using. Most sources that I have read uses sources which are in dbm (-4 dbm, -10 dbm) , I believe the appropriate source...
