Electronic analog-to-digital converter |
摘要 |
<p>The converter input i is connected through a comparator to the polarity bit output as we @ @ as to the input of a full-wave precision rectifier in the first quantization stage, which like further stages comprises an operational amplifier, a comparator and an exclusive OR gate, the output of which is connected to the output for the first bit. To the inverting input of the amplifier with the gain equal to 2 through the potentiometer a voltage -Uo/2 is fed, (-Uo, +Uo) being the interval of the input voltage. The input of the rectifier is connected to the input i and the input of the rectifier in further stages is connected to the output of the operational amplifier in the previous stage. The second input of the exclusive OR gate is connected to the bit output of the previous stage. <IMAGE></p> |
