A divide-four static frequency divider is fabricated to evaluate the ultra-high-speed performance of Au/WSiN gate GaAs MESFETs. The divider consists of two T-type flip-flops (T-F/F) ans three buffers based on low-power source-coupled FET logic (LSCFL). The divider operates up to 31.4 GHz at room temperature at power dissipation of 150 mW per T-F/F using Au/WSiN gate GaAs MESFETs well scaled down to 0.3 µm gate-length.
