Abstract :
A three-valued D-flip-flop (D-FF) circuit and a two-stage shift register built from InGaAs-based multiple-junction surface tunnel transistors (MJSTT) and Si-based metal-oxide-semiconductor field effect transistors (MOSFET) have been demonstrated. Due to the combination of the MJSTTs latching function and the MOSFETs switching function, the number of devices required for the D-FF circuit was greatly reduced to three from the thirty required for the FET-only circuit.
