摘要： This document discusses, among other things, a detection system configured to identify a type of a pole of a four-pole audio jack using first and second comparators. The detection system can include a bias circuit configured to bias a detection input coupled to the pole, and first and second comparators configured to compare the detection input to respective first and second thresholds to provide an indication of the type of the pole.

摘要： This document discusses, among other things, a MIC audio noise filtering system configured to detect MIC audio noise at a pole of a four-pole audio jack using first and second comparators. The MIC audio 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 MIC audio noise at the pole of the four-pole audio jack using the count.

摘要： This document discusses, among other things, a switching device and method configured to receive a signal at a signal input, to provide the signal at an output in a first state without an applied voltage at a first control input, and to isolate the signal from the output in a second state with an applied voltage at the first control input. In an example, the switching device can include first, second, and third transistors, wherein the source of the first transistor is coupled to the drain of the second transistor and to the gate of the third transistor, wherein the signal input is coupled to the drain of the first transistor and to the drain of the third transistor, and wherein the output is coupled to the source of the third transistor.
