A method for flattening an impedance of a power delivery network includes capturing a set of impedance parameters, obtaining an impedance of the power delivery network according to the set of impedance parameters, defining a target impedance, performing an importance calculation to determine a port, obtaining an intersection frequency according to the target impedance and the impedance of the power delivery network, selecting a decoupling capacitor according to the intersection frequency, and disposing the decoupling capacitor at the port. The method can reduce the impedance of the power delivery network to the target impedance and flatten the impedance to avoid the rogue wave phenomenon.

A noise suppression filter includes a resonator, a ground plane, and a set of differential transmission lines. The set of differential transmission lines includes a first meander line and a second meander line formed in a first circuit layer. The resonator is formed in a second circuit layer and includes a first long arm, a second long arm, and a short arm extended form a same point to form a T-shape. The ground plane is formed in a third circuit layer and is coupled to the first long arm and the second long arm through vias. The first meander line is detoured along the inner sides of the first long arm and the short arm, and the second meander line is detoured along the inner sides of the second long arm and the short arm.

Rectangular-shape resonators as guard traces formed in a region between the victim and aggressor lines are disclosed. No shorting-vias or resistors are required. The rectangular resonators are found to have functions of improving far-end crosstalk (FEXT) and timing jitter in both frequency domain and time domain if the parameters are appropriated selected.

An UHF RFID antenna for attached on any high conductive object is disclosed. The antenna radiation body has a first copper foil mounted thereon a backside surface of a FR4 glass fiber served as a ground plane, a second copper foil mounted thereon a front surface of the FR4 glass fiber as a main radiation plane. The main radiation plane contains two etched slits spaced each other. Each etched slit has a shape like a blade with a long handle. The two etched slits are mirror symmetry and a trench formed to connect the two etched slits for a RFID tag seated thereon so that There are short circuit microstrip and a feed-in microstrip are generated.

A interconnect structure includes a substrate, a pair of interconnect pads, a pair of transmission lines. The substrate is stacked with at least one layer, and each of the layers has a first surface plane and a second surface plane. The pair of interconnect pads are formed on a first surface plane of a first layer of the substrate. The pair of transmission lines is formed on the first surface plane of the first layer, and the pair of transmission lines have a Y-type close trace portion for connection to the pair of interconnect pads. Further, the first surface plane of the layer is formed with a via hole which is formed within a groin region defined by the Y-type close trace portion and extends to a second surface plane of the first layer, wherein the second surface of the first layer is a power plane or a ground plane.
