Latest Patents

One of his latest patents is an "Apparatus for improving linearity of small signal." This invention comprises at least one non-linear signal generating means that receives a first DC bias larger than a threshold voltage to generate a non-linear signal. The apparatus includes feedback means for returning the non-linear signal and amplifying means for receiving, amplifying, and outputting a second DC bias larger than the threshold voltage along with a reversed and feedback non-linear signal, effectively canceling the non-linear signal. This innovation enhances linearity and simplifies the constitution, making it suitable for various terminals.

Another notable patent is the "Method of fabricating a field emission display device having a silicon." This method involves forming a silicon tip with an undercut by creating a photoresist pattern on a silicon substrate and performing an under-cuted isotropic etching process. The process includes forming first and second insulation films on the silicon tip and substrate, with the first insulation film being separated from the second.
