Designing an Efficient Power/Control System for a Network of Piezoelectric Speakers
… individual signals requires a control system and amplifier that is as energy efficient as possible. To effectively manage so many analog channels, a multi-channel DAC was paired with a microcontroller and SD card and read out precalculated low-voltage signals for each speaker. An amplifier was …

A new mode of Class D amplification
… a more efficient method of power amplification. Class D operation, in which the output transistors are either cut off or saturated and, hence, dissipate very little power, is one method of satisfying this need. This paper presents a study of a new mode of Class D amplification. In a conventional …

An Exploratory Study of Pulse Width and Delta Sigma Modulators
… self oscillating structure, has seen use in Class D Power Amplifiers, performing a similar function. It has been shown that the PWM in Class D Amplifiers outperforms the DSM [1], but could this advantage be used in DSADC use-cases? LTSpice simulation and printed circuit board implementation …
