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.
