The automatic offset correction loop is used in the instant float-point amplifier. As the pulse amplifier, the instant float-point amplifier is used in amplifying the series of sampling pulse one by one. The design of the automatic zero-drift correction loop is based on the two-beat operating, which records a zero-drift within the interval between two samples and implements the zero-drift correction during amplifying the sample pulse by an amplifier. After applying other zero point offset corrections, the zero point offset of this equipment can reach the level of lessthan 0.25 μ V.
