Journal ArticleDOI
A micropower low-distortion digital class-D amplifier based on an algorithmic pulsewidth modulator
TL;DR: This paper simplifies the time-domain expression for the algorithmic PWM linear interpolation (LI) sampling process and analytically derive its double Fourier series expression and shows the attractive attributes of a Class-D amplifier embodying the simplified LI sampling expression and reduced clock rate pulse generator.
Journal ArticleDOI
A Randomized Wrapped-Around Pulse Position Modulation Scheme for DC–DC Converters
TL;DR: An expression for the spectrum of theRWAPPM scheme is derived to analytically obtain the peak spectral power and ripple noise voltage of RWAPPM and the derived expression further provides insight to the parameters that influence the RWAP PM spectrum.
Journal ArticleDOI
A Low-Voltage Micropower Digital Class-D Amplifier Modulator for Hearing Aids
TL;DR: The proposed digital modulator dissipates the lowest power dissipation of all modulators compared, and by means of a proposed figure of merit, the proposed modulator exhibits very competitive performance.
Journal ArticleDOI
A Noise-Shaped Randomized Modulation for Switched-Mode DC-DC Converters
TL;DR: The proposed scheme is a hybrid of a randomized modulation scheme, namely, the randomized wrapped-around pulse position modulation scheme (RWAPPM), and a noise-shaper, and an analytical expression for the input current spectrum of the hybrid scheme is derived.
Proceedings ArticleDOI
A novel sampling process and pulse generator for a low distortion digital pulse-width modulator for digital class D amplifiers
TL;DR: A novel Direct Interpolation sampling process and novel hybrid pulse generator for a Pulse Width Modulator (PWM) for a digital Class D amplifier that features the lowest harmonic distortion compared to other algorithmic sampling processes is proposed.
