Solution Overview
Problem
Conventional circuit arrangements for clocked loads lack adaptability to changing power conditions, leading to supply voltage dips when power availability decreases, as they cannot adjust clock frequency and voltage in response to fluctuating power sources like electromagnetic fields.

A circuit arrangement and method that dynamically control clock frequency and supply voltage based on measured current consumption, using a voltage limiting device and setting device to maintain a predefined power relationship, ensuring optimal operation and minimizing voltage dips by adjusting frequency and voltage in response to changing power conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If clock frequency and operating voltage are firmly predefined or set by a user, then the circuit operation is simple and stable, but the circuit cannot respond to changing power conditions leading to supply voltage dips
Solution Approach 1:
The patent implements dynamic adjustment of clock frequency and operating voltage based on real-time power availability. The control unit continuously monitors the power supply status and automatically adjusts the clock signal parameters and voltage levels to match the available power, transforming the static predefined settings into a dynamic adaptive system that responds to changing power conditions.
Solution Approach 2:
The patent introduces a feedback mechanism where the control unit monitors the actual power supply status and uses this information to adjust the clock frequency and voltage. The measurement of power availability feeds back into the control unit, which then modifies the clock signal and voltage output accordingly, creating a closed-loop system that adapts to changing conditions.
2Productivity
If clock frequency is increased to improve processing speed, then productivity increases, but current consumption increases proportionally
Solution Approach 1:
The patent dynamically changes the clock frequency parameter based on the available power supply level. When power is abundant, the system operates at higher frequencies for maximum productivity. When power becomes limited, the system automatically reduces the clock frequency to lower current consumption, ensuring that the product of frequency and power availability is optimized rather than maximizing frequency at the expense of energy.
Solution Approach 2:
The patent makes the clock frequency dynamic rather than fixed. The frequency adjusts in real-time based on power availability, allowing the system to optimize between processing speed and energy consumption. This dynamic adaptation ensures that the system achieves high productivity when possible while conserving energy when power is constrained.

AI summary
A supply power can be fed in at a circuit arrangement for supplying power to, and clocking, clocked loads. The circuit arrangement provides a clock signal at a frequency and a supply voltage, the frequency and/or the supply voltage being able to be controlled by the circuit arrangement in such a manner that a power tapped off at the output and the supply power fed in are in a predefined relationship.
