    Abstract: Examples of the present disclosure provide an electronic device in a package, the electronic device comprising a first circuit having a temperature sensitive behavior and a second circuit being switchable between a first operating mode and at least one second operating mode. A power consumption of the second circuit in the first operating mode is higher than a power consumption of the second circuit in the second operating mode. The electronic device comprises a controller configured to switch the second circuit into the first operating mode during a first time interval and into the second operating mode during a second time interval. The controller is further configured to cause an additional power consumption in the electronic device during the second time interval to reduce or compensate a difference between an overall power consumption of the electronic device during the first time interval and the second time interval.

    Abstract: A microphone or a microphone sensor system operates with a sensor interface that receives a supply voltage at a supply terminal. The sensor interface detects a command at the supply terminal based on a change in the supply voltage and communicates the command or data related to the command to a component of the sensor system. The supply terminal is a bidirectional terminal that further communicates data related to the sensor system via the supply terminal.
