Abstract: The disclosure relates to technology for generating multi-phase signals. An apparatus includes 2{circumflex over (?)}n phase signal generation stages. The apparatus also includes a controller configured to provide a mode input of each of the 2{circumflex over (?)}n stages with an active periodic binary signal with remaining inputs of each of the 2{circumflex over (?)}n stages provided with another periodic binary signal to collectively generate a 2{circumflex over (?)}n phase signal in a first mode.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a radio frequency (RF) receiver including a dual-mode low noise amplifier (LNA). One of the methods includes configuring the RF receiver to a wideband mode including operation over a multiple receive frequency (RX) bands including multiple frequencies, receiving, by the RF receiver, an input RF signal, scanning the multiple frequencies to detect a transmitted frequency of the input RF signal, configuring the RF receiver to narrowband mode including operation over a proper subset of the RX bands including a proper subset of the multiple frequencies, and tuning the RF receiver to the transmitted frequency.

Abstract: An embodiment method includes measuring, by a calibration device, a first output voltage of a variable gain amplifier (VGA) when the VGA is set at a first gain setting and measuring, by a calibration device, a second output voltage of the VGA when the VGA is set at a second gain setting different from the first gain setting. The method further includes calculating, by the calibration device, an offset voltage of a signal path including the VGA using the first output voltage and the second output voltage and calculating, by the calibration device, an internal offset voltage of the VGA using the first output voltage and the second output voltage.
