Cyclic analog-to-digital converter |
摘要 |
A method and apparatus are provided for reducing the size and power of cyclic analog-to-digital converter (ADC) conversion circuits. During each cycle, the ADC conversion circuit generates a plurality of bits. The improved ADC includes a scaling/reference circuit having a single operational amplifier which operates in a reference generation mode and an analog multiplexing mode during generation of the first bit and operates in the analog multiplexing mode during generation of the subsequent bits.
