摘要： This document discusses, among other things, a GSM noise detection system configured to detect GSM noise at a pole of a four-pole audio jack using first and second comparators. The GSM noise detection system can include first and second comparators configured to compare a value of the pole to respective first and second thresholds and to provide an output indicative of the comparisons and a detection circuit configured to count changes in the output over a first period of time and to detect GSM noise at the pole of the four-pole audio jack using the count.

摘要： This document discusses, among other things, systems and methods to reduce power use of an accessory detection device. The accessory detection device can be configured to be coupled to a mobile device having an audio jack configured to be coupled to a mobile device accessory having a send/end key. In an example, the accessory detection device can include a comparator and a switch. The comparator can be configured to receive mobile device accessory information from the mobile device accessory and to determine activation of the send/end key using the received mobile device accessory information. The switch can be configured to receive connection information indicative of mobile device accessory connection to the audio jack and to isolate a reference input of the comparator from a supply voltage using the connection information, for example, to reduce leakage current.
