An oscillator |
摘要 |
<p>A CMOS oscillator includes two differential input transistors (150) and (152) which have the sources thereof coupled through a resonator element (196). Active loads (166) and (178) provide a squaring up of the output which then drives an output transistor (202). The gates of the differential input transistors (150) and (152) are biased to predetermined voltage levels with bias circuits, with the positive input of the comparator configuration coupled through a feedback capacitor (208) to the output (204). This provides sufficient instability to initiate oscillation with a gain of the device controlled by resonator circuit (196). <IMAGE></p> |
