CMOS rectifier that operates at near to zero input voltage

millinium · Dec 10, 2013

Please help me find a efficient cmos rectifier circuit that operates at near to zero input voltage together with appropriate sizing of mos

i will really appreciate your help.

Have a look at the AD636 IC which will likely do what you are asking for:
https://www.analog.com/en/special-linear-functions/rms-to-dc-converters/ad636/products/product.html
Not strictly 'cmos', but low current and will measure virtually from Zero Volts input.

Plenty of additional data sheets and application notes on the same page further down.

hope this assists

The question is about CMOS IC design...

no harm in looking at how others have successfully implemented a device for ideas to potentially meet the requirements of the OP......

I have here my cmos rectifier circuit with RF input voltage equal to 0.25V and output rectified voltage equal to 25mV..

please help me find another cmos circuit architecture for rectifier that has high efficiency in rectifying RF signal

thanks in advance
