Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillators face interference issues during resonator examination due to the amplifier's operating conditions, which can affect the accuracy of the examination results.
Innovation Solution
A circuit device with a first switch element that switches electrical coupling between the input node and ground, allowing the amplifier to be set to an OFF state during resonator examination, thereby preventing interference and enabling accurate signal input between the first and second terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the amplifier operates during resonator examination, then the amplifier can amplify signals, but the examination results are affected by amplifier interference
Solution Approach 1:
The amplifier's operational state is made dynamic through the switch element, allowing it to be turned OFF during resonator examination to eliminate interference, and turned ON during normal signal amplification. This dynamic control resolves the contradiction by adapting the amplifier's state to the specific operational requirement.
Solution Approach 2:
The amplifier operates periodically - OFF during examination phases and ON during amplification phases. This periodic switching allows both examination accuracy and signal amplification functionality to be achieved at different time intervals without mutual interference.
2Measurement precision
If the amplifier is turned OFF to prevent interference during examination, then examination accuracy improves, but signal amplification capability is lost
Solution Approach 1:
The system dynamically switches the amplifier between OFF state during examination (ensuring measurement precision) and ON state during normal operation (maintaining signal amplification capability). The switch element enables this dynamic transition without permanent loss of functionality.
Solution Approach 2:
The amplifier alternates between examination mode (OFF) and amplification mode (ON) based on operational requirements. This periodic action ensures that measurement precision is achieved when needed while signal amplification remains available during other periods.
