Static Induction Transistor Logic

The static induction transistor logic (SITL) equivalent to PL is evaluated by fabricating type D-F/F frequency divider and 14 bit BCD programmable counter to prove its potentiality in VLSI. SITI 2 L is also implemented into LSI. The normally-configured SIT is introduced to serve as a driver transistor in the SITL having new circuit configuration in order to improve the speed performance, where output Schottky diodes are fabricated to ensure the decoupling between outputs. The performance of this Schottky SITL is evaluated in the ring oscillator, where the propagation delay is obtained 2.5 nsec at a power dissipation of 100 µW.
