摘要： An apparatus includes a radio-frequency (RF) receiver. The RF receiver includes an analog-to-digital converter (ADC) to convert an analog input signal to a digital output signal in response to an ADC clock signal. The RF receiver further includes a frequency generator to selectively provide either a clock signal to be provided as the ADC clock signal or a signal to be used for in-phase-quadrature (IQ) calibration of the RF receiver.

摘要： In one embodiment, an integrated circuit includes: a first radio frequency (RF) circuit configured to receive and process a first RF signal having a sub-gigahertz (GHz) frequency to output a first lower frequency signal and to transmit RF signals having the sub-GHz frequency; a second RF circuit configured to receive and process a second RF signal having a frequency of at least substantially 2.4 GHz to output a second lower frequency signal and to transmit RF signals at the at least substantially 2.4 GHz; shared analog circuitry coupled to the first RF circuit and the second RF circuit, the shared analog circuitry to receive at least one of the first RF signal or the second RF signal and output a digital output signal; and a digital circuit coupled to the shared analog circuit, the digital circuit to recover message information from the digital output signal.

摘要： A system and method of performing temperature compensation based on temperature of a crystal. An integrated circuit includes a clock circuit, a memory, an interface developing a sense voltage indicative of a temperature of the crystal, and a controller. The memory stores compensation values including nominal values based on a nominal third order polynomial that defines a nominal frequency versus temperature relationship of a crystal design representing multiple crystals, and a pair of adjustment values derived from two temperature-frequency error points. The controller determines a temperature value based on the sense voltage, calculates a frequency offset using the temperature value and the compensation values to solve a compensated third order polynomial defining a compensated frequency versus temperature relationship of the crystal, and adjusts a clock signal of the clock circuit using the frequency offset. A Wi-Fi device may be optimized for industrial IoT operating within an extended temperature range.

摘要： In an embodiment, an integrated circuit includes: a switched capacitor coupled between a supply voltage node and a divider node, where a thermistor external to the integrated circuit is to couple to the divider node; an analog-to-digital converter (ADC) coupled to the divider node to receive a voltage at the divider node and generate a digital value based thereon; and a controller coupled to the ADC to determine a temperature associated with the thermistor based at least in part on the digital value.
