摘要：
The idea of automatic walk stabilization for constant fraction discriminator based on compensated base line restoration is presented and tested. Comparison of this idea to gated base line restoration and other principles is discussed. It is simpler than gated base line restoration because the gated feedback loop for time equal to the input pulse width was replaced by the compensation of the input by the inverted from the LLD discriminator. The circuit is dc coupled and its operation is not limited by high frequency. The advantage of this idea in comparison to gated base line restoration is especially pronounced for very short input pulse width and high frequency when errors due to switched on/off times become important.
