Abstract
This paper describes a design technique for multi-stage high speed precision low-current consumption comparator utilizing charge-storage pre-amplifier. To reduce the average current consumption of the preamplifier capacitive dynamic load is used. To correct the offset voltage of pre-amplifier the OOS (Output Offset Storage) method is used. Presented technique is verified by design of 50 MS/s comparator in standard 0.18 μm CMOS process. Achieved power consumption of preamplifier is 18 μA, providing the input resolution less than 4 mV.
