hi everybody,
I am getting a a 400mv p-p AC source out of my ipod's audio jack. I am planning to use this to run another sensor. I want to rectify this 400 milli volt signal to a DC signal then pass it through a "LTC3108 - Ultralow Voltage Step-Up Converter and Power Manager Module"- http://www.linear.com/product/LTC3108 to boost my output voltage. What are my options to rectify such a small signal from AC to DC? I know I cannot be using ordinary full/half bridge rectifiers (because of 0.7v drop of diodes). What is a good way of AC to DC, step up conversion for max power delivery? Should I even consider using LTC3108? I was thinking of designing my own transformer where I match impedance of primary winding of transformer with impedance of audio jack for max power delivery. what do you think of that?
thanks in advance
