Abstract: An integrated receiver includes a first signal processing path, a second signal processing path, and a controller. The first signal processing path has an input and an output for providing a first processed signal, and comprises a first tracking bandpass filter having a first integrated inductor formed with windings in a first number of metal layers of the integrated receiver. The second signal processing path has an input and an output for providing a second processed signal, and comprises a second tracking bandpass filter having a second integrated inductor formed with windings in a second number of metal layers of the integrated receiver. The second number of windings is lower than the first number. The controller enables one of the first and second signal processing paths corresponding to a selected channel of a radio frequency (RF) input signal to provide an output signal.

Abstract: In one example, a semiconductor die includes multi-standard, multi-channel expandable television/satellite receiver that can be flexibly implemented in a number of different configurations to enable incorporation into a plurality of different systems. The semiconductor die may include multiple tuners to receive and tune a terrestrial radio frequency (RF) signal and a satellite RF signal. These tuners may include different frequency synthesizers including voltage controlled oscillators (VCOs) to generate VCO signals at different frequencies, mixers to downconvert the RF signals to baseband signals using the VCO signals. In an implementation, the semiconductor die may further include shared circuitry coupled to the tuners to digitize, process and demodulate the baseband signals.

Abstract: A system and method of keyword spotting using two neural networks is disclosed. The system is in sleep mode most of the time, and wakes up periodically. Upon waking, a limited duration of audio is examined. This may be performed using an auxiliary neural network. If any audio activity is detected in this duration, the system fully wakes and examines a longer duration of audio for keywords. The keyword spotting is also performed by the main neural network, which may be a convolutional neural network (CNN).

Abstract: A system and method of minimizing interference and retries in an environment where two or more network protocols utilize the same frequency spectrum is disclosed. A lower-power network controller is co-located with a WIFI controller. The lower-power network controller parses incoming packets as they are received and generates a request signal once it is determined that the incoming packet is destined for this device. This maximizes the likelihood that no WIFI traffic will occur while the incoming packet is being received.
