Abstract : A COS/MOS phase comparator was designed and breadboarded, using discrete components. When the breadboarded phase comparator was tested in a breadboarded frequency synthesizer, it showed improved performance over previous circuits. An integrated circuit (IC) version of the comparator was fabricated on a 58- by 92-mil chip. The performance of this IC was comparable to that of the breadboard circuit. A divide-by-K (K = 8) counter breadboard was constructed, using available IC's. A divide-by-N programmable counter was designed, using available IC's. An improved divide-by-R counter was designed and breadboarded. These counters met the requirements of the synthesizer system. Three voltage-controlled bipolar oscillators covering the required 225- to 400-megahertz tuning range were developed. A high-voltage bipolar loop amplifier, which eliminates the need for coarse tuning circuits in the synthesizer, was constructed and assembled. An MOS buffer amplifier was designed, breadboarded, and fabricated. It meets system requirements. (Author)
