Corrector ADC

This IP provides a DC offset removal at the ADC output, the channel amplitude and phase imbalances cancelation. The corrector is fully parameterized allows you to quickly control the speed of convergence of the each chain correction. The block diagram contains the average signal power estimator required for the subsequent removal amplitude imbalance of the channels. The synchronous sampling circuits are used to eliminate the phase error between the reception channels for the automatic gain control and diagnostics. The corrector incorporates four feedback loops, each of which is responsible for adjusting individual parameters of the complex signal from the ADC. Upon opening of the loops, the unit operates in the transmission mode to output without change.
