ABSTRACT:
A current-to-voltage interface circuit produces a first logic level voltage at an output in response to current flowing in a first input, and a second logic level voltage at the output in response to current flowing in a second input. The interface circuit has an input stage and a logic stage. The input stage has a first circuit (which includes a current input, a current source and voltage clamp, and a voltage output), a second circuit (which includes a current input, a current source and voltage clamp, and a voltage output), and a switching device connected to the logic stage input and to the two voltage outputs. The logic level voltages are produced at the output of the logic stage in response to the voltage changes at the logic stage input. The circuit transition and recovery times can be easily adjusted by proper selection of circuit components to minimize switching delays associated with decision making transitions. In a preferred combination, the interface circuit is connected to a comparator which has first and second current outputs and a preferential state in which current flows in the first current output.
