Abstract The authors have studied the oscillation frequencies in the modulators and channel converters in a Head End for cable TV. The standards used are channel 46 from the UHF range of B/G and the test channel is (n).

Abstract The similarity between the noise wave parameters and the noise parameters is studied using a noise wave model. The optimization procedures in circuit simulators is extracted using the device intrinsic circuit and available measured transistor noise parameters are related to the whole device. We have introduced an incremental extraction system using polynomial functions which is found to be more faster... The similarity between the noise wave parameters and the noise parameters is studied using a noise wave model. The optimization procedures in circuit simulators is extracted using the device intrinsic circuit and available measured transistor noise parameters are related to the whole device. We have introduced an incremental extraction system using polynomial functions which is found to be more faster and effective. In the experimentation process, the descriptive validation of the proposed procedure is carried out by comparing the transistor noise parameters of the entire circuit, obtained by using the noise wave parameters extracted by the proposed approach. For this process we have used the transistor noise parameters that studied the measures. Read More Read Less

Abstract The CMOS technology with Cadence is used to generate a two-phase switching mode for the dc converter with zero voltage switching. Further, the main power transistors-based loss is measured. We found that the effectiveness of the system increases marginally when the help of the standard two-phase dc converter architecture where we have deployed the ZVS technique....
