Wake-Up Signal Masking Circuit for Idle-State Transition Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circuit assemblies struggle to reliably recognize wake-up requests under various operation conditions, leading to potential blocked states due to non-synchronized wake-up and idle requests, especially when energy consumption needs to be minimized.
Innovation Solution
A circuit assembly with a masking circuit that interposes between the wake-up signal input and the wake-up signal, applying a masking potential in the active state and allowing the wake-up signal to pass in the idle state, ensuring reliable detection of wake-up requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the circuit is switched to idle state to reduce energy consumption, then energy savings are maximized, but the circuit cannot reliably monitor wake-up requests for a short time period
Solution Approach 1:
The circuit is designed to anticipate the monitoring gap that occurs during idle state transitions. By preparing the wake-up signal input to be monitored even during the transition period, the system performs a preliminary action that ensures no wake-up requests are missed, thereby maintaining reliability while still achieving energy savings through idle state operation.
2Use of energy by moving object
If the circuit enters idle state immediately after a wake-up request, then energy consumption is reduced, but the wake-up request may not be recognized due to temporary monitoring unavailability
Solution Approach 1:
The system implements a cushioning mechanism that protects against the loss of wake-up requests during idle state transitions. This is achieved by ensuring the wake-up signal input remains monitored during the transition period, creating a protective buffer that prevents information loss even when the circuit quickly enters idle state to reduce energy consumption.
3Ease of operation
If non-synchronized wake-up and idle requests occur, then the circuit may enter blocked states requiring full disconnection, but this increases operational complexity and user effort
Solution Approach 1:
The circuit incorporates feedback mechanisms that monitor the status of both wake-up and idle requests. When conflicting requests are detected, the system provides feedback to resolve the conflict before the circuit enters a blocked state. This feedback loop ensures reliable operation by preventing blocked states from occurring, thereby maintaining both ease of operation and reliability without requiring user intervention to disconnect the circuit.

AI summary
A circuit assembly and a method for controlling operation states The circuit can be shifted by idle signals from the active operation state into the idle state and can be shifted by wake-up signals in an edge-triggered manner from the idle state into the active operation state if the wake-up signal executes a change in potential from a non-activation potential to an activation potential. The wake-up signals are supplied to a wake-up signal input of the circuit with the interposition of a masking circuit, which passes through the wake-up signals to the wake-up signal input in the idle state of the circuit and, in the active operation state of the circuit, applies to the wake-up signal input a predetermined electric masking potential, from which a change in potential towards the activation potential of the wake-up signal shifts the circuit from the idle state into the active operation state.
