Abstract: A method and apparatus are disclosed for a configurable mixer capable of operating in a linear, a legacy, and a low-power mode. In the linear mode, the configurable mixer is configured to operate as a double-balanced mixer to multiply a first differential signal by a second differential signal. In the legacy mode, the configurable mixer is configured to as a double-balanced mixer to multiply a differential signal by a single-ended signal. In the low-power mode, the configurable mixer is configured to operate as a single-balanced mixer to multiply a differential signal by a single-ended signal. The operating mode of the configurable mixer may be based, at least in part, on a mode control signal. In some embodiments, the configurable mixer may be included in an analog front end of a wireless communication device.

Abstract: An integrated circuit is disclosed. The integrated circuit includes a primary coil. The integrated circuit also includes a first secondary coil that acts as a first transformer with the primary coil. The integrated circuit further includes a second secondary coil that acts as a second transformer with the primary coil. The primary coil the first secondary coil and the second secondary coil have a layout on the integrated circuit to minimize coupling between the first secondary coil and the second secondary coil.

Abstract: Techniques for generating oscillator signals in a wireless communication device are described. A phase-locked loop (PLL) may be used to generate an oscillator signal for a selected frequency channel. Different PLL settings may be used for the blocks in the PLL for different frequency channels. The different PLL settings may be for different PLL loop bandwidths, different amounts of charge pump current, different frequency equations associated with different sets of high and low divider ratios, different frequency division schemes associated with different prescaler ratios and/or different integer divider ratios, high side or low side injection for a super-heterodyne receiver or transmitter, and/or different supply voltages for one or more circuit blocks such as an oscillator. A suitable set of PLL settings may be selected for each frequency channel such that adverse impact due to spurs can be mitigated.
