Abstract: A frequency conversion receiver comprises a passive mixer, a Low-Noise Amplifier (LNA) and a balun. The low-noise amplifier generates an amplified single-ended signal responsive to a single-ended receiver input signal. The passive mixer generates a mixer output signal responsive to a differential mixer input signal and a four-phase local oscillator signal. The balun transforms the amplified singled-ended signal into the differential mixer input signal, the balun having a first winding coupled to an output of the low-noise amplifier and a second winding coupled to an input of the passive mixer, the second winding having more turns than the first winding. The turn ratio of the second winding to the first winding provides gain compensation to the low-noise amplifier, and in conjunction with the low-noise amplifier and the passive mixer, provides a desired gain to the receiver and linearity over a dynamic range of the receiver input signal.

Abstract: An arrangement and a method for synchronizing data to a local clock. The invention incorporates a self-tested self-synchronous two-phase input port, wherein a line or an element of parallel data is tested for data read failure using two different phases or edges of the local clock. If a data read failure is detected using one phase, the other of the two phases is selected for reading the data. The arrangement includes a data read device for reading parallel elements of the data stream using one of two different phases or edges of the local clock, a data read error detecting device arranged to sample at least one element of the data stream using the two different phases or edges of the local clock, and a decision making device.
