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: The present technique pertains to a signal processing apparatus, a signal processing method, and a receiving apparatus that enable gain control to be appropriately performed on various interfering signals.
An amplifier controls a gain according to a count value to amplify a signal, and a comparator compares the signal outputted by the amplifier with the count value. An accumulator counts the count value according to an output from the comparator. The present technique can be applied to, for example, a receiving apparatus that receives an RF signal for a television broadcast.-

Abstract: Disclosed is a low noise amplifier system. Included is a main amplifier having a main input coupled to a RF input and a main output connected to an RF output and an impedance amplifier having an impedance input coupled to the RF input and an impedance output coupled to the RF output, wherein the impedance amplifier is configured to provide input impedance matching to the main amplifier. The impedance amplifier also provides a first noise path that passes through the impedance amplifier such that the noise generated by the impedance amplifier is substantially out of phase with the noise that passes through a second noise path that passes through the main amplifier.
