Low-consumption sigma-delta DAC for audio mobile applications

A new three-level D-to-A sigma-delta converter for low consumption applications is presented. The two one-bit outputs of this converter can drive a loudspeaker directly without requiring passive components and with a sufficient audio quality. The global consumption is minimized by reducing the numbe...

Zusammenfassung:A new three-level D-to-A sigma-delta converter for low consumption applications is presented. The two one-bit outputs of this converter can drive a loudspeaker directly without requiring passive components and with a sufficient audio quality. The global consumption is minimized by reducing the number of active states.
