Disclosed herein are a transformer and a method of manufacturing the same. The transformer includes: a primary side winding having a loop shape; a secondary side winding formed on the same plane as that of the primary side winding in a remaining section except for at least a section at which it intersects with the primary side winding and having the same loop shape as that of the primary side winding so as to be electromagnetically coupled to the primary side winding; and an intersecting section formed so that the primary side and secondary side windings having the sum of the turn numbers of 3 or more intersect with each other in a two-layer structure, wherein the intersecting section includes at least one point of intermediate node having one side connected in a first layer and the other side connected in a second layer.

Disclosed herein is a capacitive touch panel having a single layer electrode structure capable of securing uniformity of capacitance distribution by decreasing capacitive coupling which may be caused by a generation of undesirable parasitic capacitance between short-range electric field lines by a sensing electrode and a ground electrode adjacent to the sensing electrode employing a mutually inclined concave and convex part toward the sensing electrode and by the sensing electrode and an adjacent driving electrode having a interdigit structure formed in the same method, in a mutual capacitive type touch panel that configures together the driving electrode and the sensing electrode on a single electrode layer having a matrix structure in which a plurality of electrodes are arranged to be intersected with each other on a base substrate.

Touch panel

Provided is a multi-band amplifier and a method of amplifying a multi-band. The multi-band amplifier includes a wireless signal input terminal into which a first frequency band signal and a second frequency band signal are input, a first impedance matching part connected to the wireless signal input terminal and configured to match an input impedance in a first frequency band, a second impedance matching part connected to the wireless signal input terminal and configured to match an input impedance in a second frequency band, a common source amplifier to which the first impedance matching part and the second impedance matching part, and a common gate amplifier connected to the common source amplifier. Accordingly, performance degradation can be reduced in comparison with a conventional amplifier, broadband amplification as well as narrow band amplification can be performed, and an amplification gain can be adjusted.
