1Strength
If a high breakdown voltage semiconductor manufacturing process is used to generate square waves with high voltage amplitude, then the voltage amplitude of the square wave is improved, but the manufacturing cost is increased
Solution Approach 1:
The voltage transition is segmented into multiple stages through the transient interval. Instead of directly switching between high and low voltages (which would require high breakdown voltage components), the circuit transitions through an intermediate transient state, dividing the voltage change into manageable steps that stay within the breakdown voltage limits of low-cost semiconductor components.
Solution Approach 2:
The transient interval acts as an intermediary state between the high voltage and low voltage states. By introducing this intermediate transition phase, the circuit avoids direct high-voltage switching that would require expensive high breakdown voltage semiconductor components, thereby enabling the use of lower-cost manufacturing processes.
2Ease of manufacture
If a low breakdown voltage manufacturing process is used to reduce manufacturing cost, then the manufacturing cost is reduced, but the ability to generate high voltage amplitude square waves is limited
Solution Approach 1:
The circuit dynamically controls the switching behavior during the transient interval to manage voltage transitions. By dynamically adjusting the switching timing and duration of the transient state, the circuit achieves high voltage amplitude square wave output while keeping instantaneous voltage differences within the breakdown voltage limits of low-cost semiconductor components.
Solution Approach 2:
The invention changes the time parameter by introducing a transient interval between high and low voltage states. This temporal parameter change allows the voltage amplitude to be high while the voltage difference at any instant remains within the breakdown voltage limits, enabling low-cost manufacturing with standard semiconductor processes.
3Device complexity
If direct voltage switching between high and low levels is performed, then the square wave generation is simplified, but the breakdown voltage is exceeded causing circuit damage
Solution Approach 1:
The transient interval serves as a protective cushion between high and low voltage states. By preparing this intermediate transition state in advance, the circuit prevents direct high-voltage switching that would exceed breakdown voltage limits and cause damage, thereby protecting the circuit while maintaining relatively simple structure.
