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.
