Abstract: A pulse width modulation (PWM) signal generator includes a quantizer for generating a quantized signal by quantizing an input signal, an asymmetric pulse width modulator, and an error correction unit. The asymmetric pulse width modulator generates an asymmetric PWM signal by comparing the quantized signal with a reference signal, with the asymmetric PWM signal being asymmetric with respect to a center of a period of the reference signal. The error correction unit is coupled between the quantizer and the asymmetric pulse width modulator to correct an error generated from the asymmetry of the asymmetric PWM signal. The quantizer is part of a delta sigma modulator having an operating frequency that is twice that of the reference signal.

Abstract: A Delta-Sigma modulator that allows for a reduction in the oversampling ratio (OSR) of a radio frequency (RF) Analog to Digital Converter. The modulator comprises a 1-bit quantizer, a N-bit quantizer and a digital quantization error correction circuit that corrects a for quantization error by using digital output signals from the 1-bit quantizer and from the N-bit quantizer, and reduces the quantization noise when the modulator transforms an analog input signal into the digital output signal. The quantization noise is reduced by ditigally correcting quantization errors, which affect the signal-to-noise ration (SNR) characteristic, using digital output signals of the multi-bit quantizer and the 1-bit quantizer. Also, a DC offset which may be generated by the multi-bit quantizer can be digitally removed.

Abstract: Disclosed is a photonic crystal organic light emitting device. The device comprises a transparent substrate having a concavo-convex structure in an upper surface thereof, a transparent electrode layer formed on the transparent substrate, a hole conduction layer comprised of an organic EL material and formed on the transparent electrode layer, an electron conduction layer comprised of an organic EL material and formed on the hole conduction layer, and a cathode layer formed on the electron conduction layer. Here, a photonic crystal period due to the concavo-convex structure formed in the upper surface of the transparent substrate corresponds to a wavelength level of light generated at an interface between the electron conduction layer and the hole conduction layer. Therefore, a light extraction efficiency and a viewing angle are increased without degeneration of the image quality. Further, since the photonic crystal has an effective refractive value ranged between that of the transparent substrate and that of the transparent electrode layer, it has the same effect as in nonreflective coating, thereby simultaneously increasing the transmittance.
