Abstract A three-state comparator is composed of 2 transistors and 4 resistors. The emitter of transistor 1 and the base of transisitor 2 are connected to form node 8. The emitter of transistor 2 and the base of transistor 1 are connected to form node 7. The collector of transistors 1 and 2 are respectively connected to resistors 5 and 6 to form nodes Ma and Mb. The nodes 7 and 8 are used as input. The nodes Ma and Mb are used as output.
