Abstract: DC offset is compensated for in an analog front end (AFE) circuit having an amplifier and an analog-to-digital converter (ADC). First data processed by the ADC are low pass filtered and estimated DC offset data of the ADC are obtained in ADC DC offset calibration mode. Second data processed by the ADC and the amplifier are low pass filtered, and a first DC offset of the ADC are substantially removed from the filtered second data by subtracting the estimated DC offset data from the filtered second data, thereby obtaining second compensated DC offset data of the amplifier in an amplifier DC offset calibration mode. The second compensated DC offset data is iteratively improved and first compensated DC offset data of the amplifier are obtained. The first compensated DC offset data are transformed into an analog signal, and the analog signal is subtracted from an input signal of the amplifier during operation mode.

Abstract: A polarizer includes a base and a plurality of grids arranged on a surface of the base parallel to one another. Each of the grids comprises an intermediate layer and a semi-transmissive metal layer that reflects a part of external light incident thereon and transmits a part of the external light incident thereon. The semi-transmissive metal layer and the intermediate layer are alternately deposited to include at least two semi-transmissive metal layers. The thicknesses of the semi-transmissive metal layers increases in a direction in which the semi-transmissive metal layer is disposed away from the external light. An organic light emitting display apparatus includes the polarizer and has improved contrast and brightness.

Abstract: A half-bridge three-level pulse width modulation (PWM) amplifier includes a prescaling unit, a PWM generator configured to convert the input signal to a three-level PWM signal having a first level, a second level and a reference level and an output stage. The prescaling unit scales an input signal according to at least one gain value to provide a scaled signal. The PWM generator varies the width of pulses having the first level and varies the width of pulses having a second level based on the scaled signal. The output stage drives an output node to a level of a first power supply voltage, a second power supply voltage or a third power supply voltage based on the three-level PWM signal. The output node is connected to a load. The magnitude of the at least one gain value compensates for variations of power supply voltages.

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: Example embodiments relate to a voltage converter having a power switching unit, an analog-digital converting (ADC) unit, a digital low pass filter (LPF), an error value (EV) calculator, and a switching signal generator. The power switching unit may generate an output voltage by switching between an output terminal and one of the power voltage and the ground voltage in response to a switching signal. The ADC unit may output a converted power level signal and a converted output level signal. The EV calculator may generate an EV by comparing a low pass filtered power level signal and a low pass filtered output level signal output from the digital LPF, and an output set value. The switching signal generator may generate the switching signal for adjusting a time interval during which the output terminal is connected to one of the power voltage and the ground voltage.
