Power Saving Circuit Regulator for Cross-Talk Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power saving circuits suffer from limited cross-talk control and interference decoupling, leading to variance in power requirements between circuits, which can result in improper operation and inefficient power use due to dynamic current or voltage fluctuations.
Innovation Solution
A power saving circuit with a regulator and voltage controlling circuits that compare reference voltages with node voltages to adjust current supply, using amplifiers and transistors to maintain a constant voltage at a node between two circuits, thereby isolating dynamic current usage and reducing interference.

If circuits are configured in a power sharing arrangement, then power efficiency is improved, but cross-talk and interference between circuits increase
Solution Approach 1:
A regulator circuit is introduced as an intermediary between the first and second circuits in the power sharing configuration. The regulator monitors the voltage at the shared node and actively adjusts current flow to maintain voltage stability, thereby preventing cross-talk and interference while preserving power efficiency benefits.
Solution Approach 2:
The regulator implements a feedback mechanism by continuously monitoring the voltage at the shared node between the two circuits. When voltage deviates from the reference level, the regulator adjusts its current flow accordingly, creating a closed-loop control system that maintains voltage stability and isolates circuits from each other's fluctuations.
2Object-affected harmful factors
If voltage regulation is implemented at a shared node, then cross-talk control is improved, but device complexity increases
Solution Approach 1:
The regulator serves as a dedicated intermediary component that handles all voltage regulation functions at the shared node. By concentrating the regulation function in a single module rather than distributing complexity across both circuits, the overall system complexity is managed more effectively while achieving superior cross-talk control.

AI summary
A power saving circuit (PSC) may include a first circuit and a second circuit electrically coupled in series in a power sharing configuration. The PSC may further include a regulator that is electrically coupled to a first node when the first circuit requires less current or the second circuit supply current to the first node when the first circuit requires less current or the second circuit requires more current, and the regulator can remove current from the first node when the first circuit requires more current or the second circuit requires less current.
