Abstract : A COS/MOS phase comparator was designed and breadboarded, using discrete components. When the phase comparator was tested in a breadboarded frequency synthesizer, it showed improved performance over previous circuits. An IC layout for the comparator was completed, and preparation of masks was started for fabricating the circuit on a 63- by 70-mil chip. A divide-by-K (K = 4) counter breadboard was constructed, using available IC's. This counter met system requirements. A divide-by-N programmable counter was designed, using available IC's. This counter met system requirements. The possibility of reducing the required number of IC's from 15 to six was investigated. (Author)
