    Abstract: Example embodiments of the invention may provide systems and methods for multiple transformers. The systems and methods may include a first transformer that may include a first primary winding and a first secondary winding, where the first primary winding may be inductively coupled to the first secondary winding, where the first transformer may be associated with a first rotational current flow direction in the first primary winding. The systems and methods may further include a second transformer that may include a second primary winding and a second secondary winding, where the second primary winding may be inductively coupled to the second secondary winding, where the second transformer may be associated with a second rotational current flow direction opposite the first rotational current flow direction in the second primary winding, where a first section of the first primary winding may be positioned adjacent to a second section of the second primary winding, and where the adjacent first and second sections may include a substantially same first linear current flow direction.

    Abstract: In a method of forming a pattern and a method of forming a capacitor, an oxide layer pattern having an opening is formed on a substrate. A conductive layer is formed on the oxide layer pattern and the bottom and sidewalls of the opening. A buffer layer pattern is formed in the opening having the conductive layer, the buffer layer pattern including a siloxane polymer. The conductive layer on the oxide layer pattern is selectively removed using the buffer layer pattern as an etching mask. A conductive pattern having a cylindrical shape can be formed on the substrate. The method of forming a pattern may simplify manufacturing processes for a capacitor and a semiconductor device, and may improve their efficiencies.

    Abstract: Embodiments of the present invention may provide for a long delay generator for the spectrum sensing of cognitive radio systems. The long delay generator may comprise of an Analog-to-Digital Converter (ADC), memory element, and Digital-to-Analog Converter (DAC). The memory element may utilize shift register bank or Random-Access Memory (RAM) cells. The long delay generator may provide for a selectable delay by digitizing the received signal, delaying the received signal in the digital domain, and reconstructing the delayed signal as an analog. The analog delayed signal may then be compared or otherwise correlated with the original input signal using an analog auto-correlation technique to determine whether a meaningful signal type has been identified or otherwise detected.
