Patent ID: 8705304

Claim:
A current mode sense amplifier, comprising: first and second input/output nodes; cross-coupled transistors, a first transistor of the cross-coupled transistors coupled to the first input/output node and a second transistor of the cross-coupled transistors coupled to the second input/output node; a load circuit coupled to the cross-coupled transistors and to a ground and configured to provide a resistance to control at least in part the loop gain of the current mode sense amplifier, the load circuit including a first resistor coupled to a first transistor of the cross-coupled transistors and a second resistor coupled to a second transistor of the cross-coupled transistor; a latch mode circuit coupled to the pair of cross-coupled transistors and to the ground, the latch mode circuit configured to increase a loop gain of the current mode sense amplifier when activated; and wherein a state sensed by the current mode sense amplifier is latched based on the latch mode circuit being activated and the load circuit being deactivated.
