A high-speed potential of an n+-Ge gate AlGaAs/GaAs MISFET has been confirmed by a ring oscillator and a frequency divider performances. The circuit was based on SCFL with 1.0 µm gate-length MISFET's. The delay time was 42.4 ps with a power dissipation of 8.9 mW/gate. A maximum toggle frequency of 11.3 GHz with a power dissipation of 219 mW per T-F/F has been achieved at room temperature.
