Abstract
A rectifier circuit () for a passive RFID circuit (), including: a first rectifier stage () having a positive stage input () connectable to a first antenna port () and a negative stage input () connectable to a second antenna port (); a first rectifying unit () connected to the positive stage input () and to a positive stage output (); a second rectifying unit () connected to the negative stage input () and to a negative stage output (); and a trimming capacitor () connected to the positive stage input () and to the negative stage input (). The trimming capacitor () is electronically switchable to a first capacitance and to a second capacitance, and a voltage dependent variable capacitor () is connected to the positive stage input () and to the negative stage input ().
