Bubble memory sense amplifier

摘要

A sense amplifier which is fully integrated has an on-chip voltage regulator to provide essentially error free operation. The sense amplifier provides peak-to-peak signal detection for comparison to a threshold voltage by a comparator. The output of the comparator is coupled to an RS flip-flop. The output of the RS flip-flop is coupled to a D flip-flop. The use of an RS flip-flop as well as a D flip-flop eliminates clocking problems caused by skewing and keeps a stored detected signal from changing prematurely.
