Hi,
I want to design a rectifier using schottky diode (HSMS285x) for an ultra low input power (-20dBm) at 700MHz.
It is strange that efficiency is better with single diode than voltage doubler circuit or/and bridge diode, although half-wave is lost in single diode circuit!!!
but on high input power level (>10dBm), efficiency is direct proportion to the number of stages and diodes However, on the low input power level is in the inverse proportion.
why?!!
