AI Technical Summary
Technical Problem
The operating frequency of existing time-interleaved slope analog-to-digital converters is limited.
Method used
An analog-to-digital converter, comprising first and second slope signal generators and a comparator, is used to compare the two slope signals by phase difference to generate an output signal, thereby reducing the operation cycle.
Benefits of technology
This increases the operating frequency of the analog-to-digital converter, reduces the conversion time to less than half of the maintenance time, and improves operating efficiency.

Abstract
This application relates to an analog-to-digital conversion apparatus and an analog-to-digital conversion method. The analog-to-digital conversion apparatus includes a first slope signal generator, a second slope signal generator, and a comparator. The first slope signal generator generates a first slope signal, wherein the first slope signal rises and falls within a voltage range at least with a first slope. The second slope signal generator generates a second slope signal, wherein the second slope signal rises and falls within a voltage range at least with a second slope, and wherein there is a phase difference between the first slope signal and the second slope signal. The comparator generates an output signal based on the first slope signal, the second slope signal, and an input signal.
