摘要： Certain aspects of the present disclosure provide methods and apparatus for performing quadrature combining and adjusting. One example circuit may include first through fourth mixing circuits. The first mixing circuit may multiply a radio frequency signal with a first local oscillating signal to generate a first frequency converted signal. The second mixing circuit may multiply a radio frequency (RF) signal with a second local oscillating signal, which may be about 90° out of phase with the first local oscillating signal, to generate a second frequency converted signal. The third and fourth mixing circuits may multiply the RF signal with the second and first signals, respectively, to generate third and fourth frequency converted signals, respectively. A first combining circuit may combine the first and third frequency converted signals, and a second combining circuit may combine the second and fourth frequency converted signals.

摘要： A user device determines whether a device connected to its headset jack is an audio accessory device. If the device connected to the headset jack is an audio accessory, the user device connects one or more pins of the headset jack to an audio codec. If the device plugged into the headset jack is not an audio accessory device, the user device connects one or more pins of the headset jack to alternate circuitry. The user device then determines, through the alternate circuitry, an electrical operating parameter requirement of the accessory device, and provides, from the alternate circuitry, the required operating parameter to the accessory device through the headset jack. The alternate circuitry may include an adjustable voltage regulator and/or an adjustable current regulator and the required operating parameter may be one or more of a voltage supply and a current supply.
