Abstract
A sensor with a dynamic latch comprising having a sensor coupled to a gain amplifier, a delay circuit connected to the gain amplifier and a summing circuit coupled through first and second nodes to the gain amplifier. The sensor with a dynamic latch further comprises an output stage coupled to a comparator circuit and the summing circuit and to third and fourth nodes and first and second energy storing devices coupled to the comparator circuit.
Claims24
A sensor dynamic latch arrangement comprising:
- a sensor;
- first and second nodes coupled to the sensor;
- a regenerative latch arranged to couple the first and second nodes to third and fourth nodes, wherein the regenerative latch provides output signals on the third and fourth nodes dependent upon input conditions on the first and second nodes, wherein the regenerative latch is arranged to remember the output signals upon a power interruption, and wherein the regenerative latch is arranged to regenerate the input conditions and the output signals following the power interruption;
- and,
- an output stage coupled to the third and fourth nodes.
