First Claim
Patent Images
1. An input signal settling system for use in an analog to digital converter (“
- ADC”
) system, the input signal settling system comprising;
an ADC comprising an ADC input port;
a high accuracy component configured to settle a first input signal with high accuracy and to communicate said high accuracy settled signal to said ADC input port;
a resistor configured between an output of said high accuracy component and said ADC input port; and
a high speed component configured to settle said first input signal with high speed and in parallel with said high accuracy component and to communicate said high speed settled signal to said ADC input port.

Abstract
A method and device are configured for providing for both quick and accurate signal settling. A high accuracy component is configured in parallel with a high speed component. The high accuracy component may be an op-amp. The high speed component may be an OTA that is configured to be a non-linear OTA. Furthermore, an ADC is configured to internally provide both quick and accurate signal settling. For example, an ADC comprises an internal high speed OTA configured in parallel with a connected external op-amp. The OTA is configured to be a non-linear OTA.
