Abstract
An analog-to-digital converter (ADC) is provided. The ADC comprises an input terminal configured to receive input signals, a digital-to-analog converter (DAC), a first switch configured to control a connection between the DAC and the input terminal, a comparator, a second switch configured to control a connection between the DAC and the comparator, and a controller configured to control the first switch, the second switch, the DAC and the comparator.
Claims23
An analog-to-digital converter (ADC) comprising:
- an input terminal configured to receive input signals;
- a digital-to-analog converter (DAC);
- a first switch configured to control a connection between the DAC and the input terminal;
- a comparator;
- a second switch configured to control a connection between the DAC and the comparator;
- and
- a controller configured to control the first switch, the second switch, the DAC and the comparator.
An analog-to-digital conversion method comprising:
- receiving input signals at an input terminal;
- controlling, by a first switch, a connection between a digital-to-analog converter (DAC) and the input terminal;
- controlling, by a second switch, a connection between the DAC and a comparator;
- and
- controlling, with a controller, the first switch, the second switch, the DAC and the comparator.
An analog-to-digital converter (ADC) comprising:
- a digital-to-analog converter (DAC);
- a controller;
- a path switching circuit configured to alternately change nodes of the DAC connected to the controller and nodes of the DAC connected to one or more input terminals;
- wherein the DAC comprises a first capacitor group comprising one or more capacitors connected to a first common node and a first control input terminal, and a second capacitor group comprising one or more capacitors connected to a second common node and a second control input terminal;
- wherein the DAC samples an input analog signal and determines a conversion signal based on the analog signal;
- and
- wherein the controller adjusts the conversion signal and generates a digital output corresponding to the analog input.
