In this paper, we discuss logic circuit designs using the circuit model of three-state quantum dot gate field effect transistors (QDGFETs). QDGFETs produce one intermediate state between the two normal stable ON and OFF states due to a change in the threshold voltage over this range. We have developed circuit model which has intermediate state. Various logic can be implemented using QDGFETs. In this paper, we have discussed the designs of various three-state QDGFET combinational circuits like decoder, and comparator. Increased number of states in three-state QDGFETs will increase the number of bit-handling capability of this device and will help us to handle more number of bits at a time with less circuit elements.
