Abstract: Disclosed is an electronic device which includes an audio processing block for voice recognition in a low-power mode. The electronic device includes a digital microphone that receives a voice signal from a user and converts the received voice signal into a PDM signal, and a DMIC interface circuit. The DMIC interface circuit includes a PDM-PCM converting block that converts the PDM signal into a PCM signal, a maxscale gain tuning block that tunes a maxscale gain of the PCM signal received from the PDM-PCM converting block based on a distance information indicating a physical distance between the user and the electronic device acquired in advance of the converting of the PDM signal, and an anti-aliasing block that performs filtering for acquiring voice data of a target frequency band associated with a PCM signal output from the maxscale gain tuning block.

Abstract: An audio device includes a channel detection electrode and a jack detector configured to determine whether the channel detection electrode is in contact with a jack according to voltage variation of a detection node. The jack detector includes a first resistor coupled between the detection node and a first node to which a first voltage is supplied, a second resistor coupled between the detection node and the channel detection electrode, a third resistor coupled between the detection node and a second node, and a comparator configured to compare a voltage at the detection node with a reference voltage.
