SUCCESSIVE APPROXIMATION REGISTER ANALOG-TO-DIGITAL CONVERTER WITH EMBEDDED FILTERING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240113724 titled 'SUCCESSIVE APPROXIMATION REGISTER ANALOG-TO-DIGITAL CONVERTER WITH EMBEDDED FILTERING
Simplified Explanation
The abstract describes an analog-to-digital converter (ADC) that includes a switched capacitor circuit, a comparator, and a control circuit. The switched capacitor circuit samples an analog input signal and provides an output signal based on a digital sample value output by the ADC.
- Switched capacitor circuit:
- Includes switches coupled to capacitors - Provides output signal based on analog input signal sample
- Comparator:
- Compares output of switched capacitor circuit - Has an output
- Control circuit:
- Provides switch control signals to switched capacitor circuit - Receives input from comparator - Generates switch control signals based on input

Original Abstract Submitted
an analog-to-digital converter (adc) includes a switched capacitor circuit, a comparator, and a control circuit. the switched capacitor circuit has a switch control input and an output, and includes switches coupled to the switch control input and coupled to capacitors. the comparator has an input coupled to the output of the switched capacitor circuit and has an output. the control circuit has a switch control output coupled to the switch control input, has an input coupled to the output of the comparator, and provides switch control signals at the switch control output. responsive to the switch control signals, the switched capacitor circuit provides an output signal to the comparator that is based on a sample of an analog input signal acquired in a sample acquisition cycle and based on a digital sample value output by the adc prior to the sample acquisition cycle.
