Abstract
A radio frequency rectifier circuit may include a resistive termination to circuit ground, a plurality of inductors, and at least a first pair of rectifier components. The plurality of inductors may be connected electrically in series between an input node for receiving an input RF signal and the resistive termination. Each pair of electrically adjacent inductors of the plurality of inductors may be connected together at a respective in-line node. The first pair of rectifier components may electrically couple a first one of the in-line nodes to a respective direct current output node. Each rectifier component may have a cathode and an anode. A first rectifier component of the first pair of rectifier components may have the cathode electrically connected to the first in-line node and a second rectifier component of the first pair of rectifier components may have the anode electrically connected to the first in-line node.
