In this paper, yield improvement methodology is proposed for RF substrates with embedded RF passive circuitry. The proposed methodology introduces a concept of package-chip co-design and on-chip calibration of active circuitry for the yield improvement of off-chip passive embedded RF filters. RF receiver architecture for the package-chip co-design and on-chip calibration technique is presented. Using...
A low-cost test method is proposed for testing integrated radio-frequency (RF) substrates with embedded RF passive filters. The proposed method enables the testing of embedded high-frequency gigahertz filters by the analysis of low-frequency signal of the order of 100 MHz. In addition, the test method allows the testing without injecting external test stimulus into RF filters. Hence, significant reduction...
In this paper, a novel low-cost method for testing embedded passive filters in integrated radio frequency (RF) substrates is introduced. The introduced test method does not require external test stimulus and enables testing of these embedded RF passive circuits without vector network analyzer (VNA). The core principle of the proposed test method relies on including the passive filter through substrate...
Unimodular filterbanks (UMFBs) have the lowest possible system delay of M - 1 samples, where M is the number of channels. In this paper we make use of this property to show that finite length signals can be processed using UMFBs without any border distortions. More specifically, we show that perfect reconstruction (PR) is achieved without increasing the number of samples at the analysis output, and...
