Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a high power source voltage is used to generate higher control voltages for sense amplifier transistors, then the control voltages can reach the required magnitude, but the stabilization time increases
Solution Approach 1:
The voltage generation is divided into two separate current circuits: a first current circuit generates an intermediate voltage using a first power source voltage, and a second current circuit generates the final high control voltage using a second power source voltage. This segmentation allows the stabilization process to occur in stages, reducing the overall stabilization time while achieving the required voltage magnitude.
Solution Approach 2:
The first current circuit acts as an intermediary by generating an intermediate voltage that serves as a basis for the second current circuit to generate the final high control voltage. This intermediary step enables the system to reach high voltages more quickly by building upon a partially stabilized intermediate voltage rather than starting from zero.
2Loss of time
If multiple current circuits and amplifier circuits are added to improve voltage stabilization speed, then the stabilization time decreases, but the device complexity increases
Solution Approach 1:
The first current circuit serves multiple functions: it generates an intermediate voltage for the second current circuit, provides a preliminary stabilized voltage reference, and contributes to the overall voltage generation process. This multi-functionality reduces the need for completely separate circuits, thereby limiting the increase in device complexity while achieving faster stabilization.
