20090075622 | OFFSET CORRECTION FOR PASSIVE MIXERS - A downconversion mixer includes a configurable gate or bulk bias voltage to allow calibration and correction of device offsets. Calibration may be performed on the configurable bias voltages to minimize IM2 distortion in the mixer. The techniques have minimal impact on voltage headroom, impose no requirement for a signal path to be phase-matched with a calibration path, and are particularly well-suited for passive mixers. | 03-19-2009 |
20090130994 | ADJUSTABLE LOCAL OSCILLATOR PATH IN A COMMUNICATION DEVICE WITH A TRANSMITTER - A communication device includes a transmitter and a receiver. The receiver mixes a local oscillator (LO) signal with the received signal to downconvert the received signal to an intermediate frequency (IF). The LO path that feeds the LO signal to the downconverting mixer is controlled based on the transmit power of the transmitter. For high transmit power, the drive of the LO path is increased, thereby increasing the signal-to-noise ratio of the LO signal input into the mixer. For low transmit power levels, the drive to the LO path is decreased, reducing power consumption in the communication device. In this way, receiver path noise due to mixing of the LO phase noise with the self-generated transmitter signal is selectively controlled while incurring lower power consumption penalty. The communication device may be an access terminal configured for communication with a cellular radio network. | 05-21-2009 |

These impedances can be configured such that the on impedance of the first low noise amplifier equals the combined impedance of the off impedance of the second low noise amplifier and the balancing impedance. This balancing of impedances on the first and second primary coils results in power supply rejection of noise and spurious signals. | 10-24-2013 |

In an exemplary design, the shunt switch is isolated from the I/O pad by a series switch. The series switch and the shunt switch may be closed when the amplifier is disabled and may be opened when the amplifier is enabled. | 04-24-2014 |
20140139042 | PORT ISOLATION IN SHARED TRANSFORMERS - Techniques for improving performance of a transformer shared amongst a plurality of operating modes. In an aspect, first and second primary windings of a transformer are coupled to an AC ground voltage. Primary windings are mutually coupled to a secondary winding of the transformer. To render the second primary winding inactive, e.g., when operating in a first mode, a switch coupling the second primary winding to the common reference voltage is opened. Similarly, when it is desired to render the first primary winding inactive, e.g., when operating in a second mode, a switch coupling the first primary winding to the common reference voltage is opened. In this manner, the inactive primary winding advantageously does not load the secondary winding. Further aspects provide for, e.g., extending the techniques to more than two modes, and alternative techniques to mutually couple the signal from the primary to the secondary winding. | 05-22-2014 |
