Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ADC systems face challenges in efficiently switching between different operating modes without requiring power cycling or rebooting, which can disrupt system continuity and increase switching time.
Innovation Solution
The proposed ADC system includes hardware circuitry and a controller that allows switching between two operating modes by transmitting configuration and calibration information to the hardware circuitry, enabling operation in the second mode without rebooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power cycling or rebooting is performed to switch between operating modes, then hardware circuitry configuration can be changed, but system downtime increases and continuity is disrupted
Solution Approach 1:
The patent stores multiple hardware circuitry configuration profiles in memory before switching is needed. When a mode change is requested, the pre-stored configuration data is immediately loaded and applied, eliminating the need for time-consuming power cycling or rebooting sequences. This preliminary preparation of configuration states enables instantaneous mode switching while maintaining system continuity.
2Adaptability or versatility
If power cycling or rebooting is performed to switch between operating modes, then hardware circuitry configuration can be changed, but system stability is reduced
Solution Approach 1:
Configuration profiles are prepared and validated in advance while the system operates in its current mode. The new configuration is held in memory and only applied when explicitly triggered, allowing the system to maintain stable operation in the current mode while being ready for seamless transition. This eliminates the instability caused by abrupt power cycling or rebooting events.
3Adaptability or versatility
If traditional mode switching is performed, then operating mode can be changed, but calibration information must be re-acquired
Solution Approach 1:
The patent creates a universal calibration information structure that is associated with each hardware circuitry configuration profile. When a mode switch occurs, the corresponding calibration information is automatically retrieved from memory alongside the configuration data. This multi-functional approach allows the same calibration infrastructure to serve multiple operating modes without requiring re-calibration, saving time and maintaining measurement accuracy across mode transitions.

AI summary
An analog-to-digital converter (ADC) system for switching between a first operating mode and a second operating mode, where both the first operating mode and the second operating mode can include post-calibration analog-to-digital conversions, where a hardware circuitry configuration of the second operating mode can differ from a hardware circuitry configuration of the first operating mode, can include hardware circuitry. The ADC system can also include a controller, which can be configured to control the hardware circuitry to control switching between the first operating mode and the second operating mode in response to a command to switch from the first operating mode to the second operating mode. This can include to transmit second mode configuration information and second mode calibration information to the hardware circuitry, where the second mode configuration information can include values to configure the hardware circuitry to operate in the second operating mode and the second mode calibration information can include values to calibrate the ADC system while operating in the second operating mode.
