Patent ID: 8415837

Claim:
A very lower power RF voltage rectifier, comprising: differential positive and negative inputs; a load; and a switching mode CMOS gate cross-connected bridge connecting said differential input to said load, said CMOS gate cross-connected bridge comprising, a first series path from the positive input through a first near zero threshold PMOS switching transistor and first near zero-threshold NMOS blocking transistor to one of ground or a load; a second series path from the negative input through a first near zero-threshold NMOS switching transistor and second near zero-threshold PMOS blocking transistor to the other of said load and said ground; a third series path from between the negative input through a third near zero-threshold PMOS switching transistor and a third near zero-threshold NMOS blocking transistor to said one of ground or a load; and a fourth series path from the positive input through a fourth near zero-threshold NMOS switching transistor and fourth near zero-threshold PMOS blocking transistor to the other of said load and said ground.
