Abstract: An example method of operation may include initiating an automated tuning procedure, detecting via one or more microphones a sound measurement associated with an output of one or more speakers at two or more locations, determining a number of speech transmission index (STI) values equal to a number of microphones, and averaging the speech transmission index values to identify a single speech transmission index value.

Abstract: A method for calibrating an isolator product includes receiving a calibration signal on a differential pair of nodes of a receiver signal path of a first integrated circuit die of the isolator product. The method includes generating a diagnostic signal having a level corresponding to an average amplitude of the calibration signal on the differential pair of nodes. The method includes configuring a programmable receiver signal path based on the diagnostic signal. Generating the diagnostic signal may include providing an analog signal based on a full-wave rectified version of the calibration signal on the differential pair of nodes. Generating the diagnostic signal may include converting the analog signal to a digital signal.

Abstract: An exemplary structure has an output stage; a driver stage; and a power stage connected between the driver stage and the output stage. The power stage includes a first transistor and a second transistor connected in series between the driver stage and the output stage. The power stage also includes a third transistor and a fourth transistor connected in series between the driver stage and the output stage. An inductor has a first terminal electrically connected to a first node between the first transistor and the second transistor and a second terminal electrically connected to a second node between the third transistor and the fourth transistor. The inductor is configured to provide impedance matching between common-gate stages of the power stage.

Abstract: A feedforward echo cancellation device includes: a first impedance circuit for responding to a transmission current to output a first current to a node; an echo cancellation current generating circuit for drawing an echo cancellation current from the node; a circuit module that is coupled to the echo cancellation current generating circuit and the node has a first impedance value adjusted based on a system convergence index of a communication device, where the first impedance value is used to determine a gain of a programmable gain amplifier in the communication device; and a second impedance circuit for responding to the transmission current to output a second current to the node, where a second impedance value of the second impedance circuit is adjusted based on the first impedance value of the circuit module accordingly. Specifically, the node is coupled to an input terminal of the programmable gain amplifier.
