В работе представлены результаты проектирования четырех микросхем квадратурных модуляторов и демодуляторов, в которых реализована коррекция динамических параметров цифровым способом, что достигается регулировкой режимов работы отдельных функциональных блоков схемы. Разработаны опытные образцы квадратурных модуляторов и демодуляторов на основе SiGe технологического процесса и приведены результаты измерений. Показано, что при регулировке изменение фазового разбаланса может достигать значений до 5°, амплитудный разбаланс - до 2,8 дБ, а подавление паразитных составляющих может быть больше 50 дБ. The paper presents four quadrature modulators and demodulators circuits design results. In these circuits the dynamic parameters are digitally corrected, which is achieved by adjusting the operation modes of separate functional blocks. Prototypes of quadrature modulators and demodulators manufactured on SiGe process were produced and the measurement results are presented. It is shown that during adjustment the change in phase imbalance can reach values up to 5 degrees, amplitude imbalance up to 2.8 dB, and suppression of spurious components can be more than 50 dB.

Similarity And Difference

Performance-measure weights for incentive compensation are often determined subjectively. Determining these weights is a cognitively difficult task, and archival research shows that observed performance-measure weights are only partially consistent with the predictions of agency theory. Ittner et al. (2003) have concluded that psychology theory can help to explain such inconsistencies. In an experimental setting based on Feltham and Xie (1994), we use psychology theories of reasoning to predict distinctive patterns of similarity and difference between optimal and actual subjective performance-measure weights. The following predictions are supported. First, in contrast to a number of prior studies, most individuals' decisions are significantly influenced by the performance measures' error variance (precision) and error covariance. Second, directional errors in the use of these measurement attributes are relatively frequent, resulting in a mean underreaction to an accounting change that alters performance measurement error. Third, individuals seem insufficiently aware that a change in the accounting for one measure has spillover effects on the optimal weighting of the other measure in a two-measure incentive system. In consequence, they make performance-measure weighting decisions that are likely to result in misallocations of agent effort.
