Abstract: A two-stage, passive, RC polyphase filter for mm-wave quadrature LO generation is presented. The filter features an innovative, symmetrical layout structure, which is more robust to parasitics than the conventional layout. Layout parasitics which become important at mm-wave frequencies are identified and a compensated. Impedance variations and transfer functions are evaluated considering these dominant parasitics. More than 15 dB improvement in image rejection ratio is achieved in comparison with conventional layouts. Using the inventive techniques more than 35 dB of image rejection ratio over a bandwidth of 6 GHz is demonstrated in an outphasing transmitter at 60 GHz in 40 nm CMOS.

Abstract: A wireless communication apparatus is arranged to detect, among a plurality of modulated carrier signals of different frequencies, at least one of the modulated carrier signals modulated with a tone burst. A receiver provides a composite signal comprising the plurality of modulated carrier signals received simultaneously. An ADC generates samples of the composite signal, and the samples of the composite signal are divided into a plurality of blocks. The samples of each block are transformed into frequency domain components, and the frequency domain components of each block are divided into a plurality of groups, each group corresponding to a range of frequencies occupied by a different one of the modulated carrier signals. Tone burst detection is performed on each group, and it is determined which of the modulated carrier signals is modulated with the tone burst, according to which of the groups the tone burst is detected in.

Abstract: According to a method of Successive Approximation Register (SAR) analog to digital conversion, N+1 SAR cycles are performed to obtain an output digital code having N bits. An analog signal is sampled and obtained. After execution of the first N−1 SAR cycles, the Nth SAR cycle is performed by setting a Nth tentative analog signal corresponding to a provisional digital code and comparing the Nth tentative analog signal with the sampled analog signal to obtain a Nth comparison result. The (N+1)th SAR cycle is performed by setting a (N+1)th tentative analog signal based on the Nth comparison result, comparing the (N+1)th tentative analog signal with the sampled analog signal to obtain a second comparison result, and correcting the provisional digital code based on the (N+1)th comparison result to obtain the output digital code. The Nth and (N+1)th SAR cycles each comprise a plurality sub-comparisons and yield a set of sub-results.
