Abstract :
A silicon bipolar divide-by-eight static frequency divider was developed. A state-of-the-art advanced borosilicate-glass self-aligned (A-BSA) transistor technology that has a cutoff frequency of 40 GHz at Vce=1 V was applied. Optimum circuit and layout designs were carried out for high-speed/low-power operation. The single-ended input realized by an on-chip metal-insulator-metal (MIM) capacitor makes it easy to use in microwave applications. Ultrahigh-speed operation, up to 21 GHz, was realized, with 320-mW power dissipation from a single +5-V supply. The static frequency divider is a suitable prescaler for phase-locked oscillators (PLOs), completely covering microwave frequencies from L band through Ku band (1-18 GHz)
