Title (EN) IMPROVED OSCILLATOR CIRCUIT AND METHOD OF FORMING SAME
(FR) MONTAGE OSCILLATEUR AMELIORE ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)An oscillator circuit (100) provides improved noise immunity by utilizing a differential common base configuration. The oscillator includes a differential transistor pair (102, 104) having common bases (110) coupled through an AC ground (108) and emitters coupled through a differential common mode point (120). First and second resonant tank circuits are each referenced to the differential common mode point (120) for generating a differential output (OUT, OUTX).
(FR)La présente invention concerne un montage oscillateur (100) offrant une tenue au bruit améliorée grâce à l'utilisation d'une configuration de base commune. Cet oscillateur comprend une paire de transistors différentiels (102, 104) possédant des bases communes (110) couplées par une masse a.c. (108) et des émetteurs couplés par un point en mode commun différentiel (120). Des premier et second circuits bouchons sont chacun rattaché au point en mode commun différentiel (120) pour produire une sortie différentielle (OUT, OUTX).
