Introduction
1. Standard Overview
GB/T 14028—2018 "Semiconductor Integrated Circuit Analog Switch Test Methods" comprehensively specifies the parameter test methods for bipolar, MOS, and junction field effect semiconductor integrated circuit analog switches, and is suitable for multiplexer parameter testing.
2. Comparison of standard frameworks
| Standard version | New content | Modified content | Scope of application |
|---|---|---|---|
| GB/T 14028—92 | - | - | Basic principles of analog switch test methods |
| GB/T 14028—2018 | Added test methods for parameters such as on-resistance path difference rate and temperature drift rate | Modified test environment requirements and table expression format | Semiconductor integrated circuit analog switches and multiplexers |
3. Background of Standard Formulation and Technological Evolution
With the advancement of semiconductor technology, the application scenarios of analog switches are becoming increasingly extensive. The revision of GB/T 14028 reflects the industry's demand for higher precision and more comprehensive test methods.
This standard is based on the drafting rules of GB/T 1.1-2009 and absorbs the experience of international advanced test methods.
4. Interpretation of Key Parameters and Practical Applications
Case: Measurement of On-Resistance Channel Difference Rate
The On-Resistance Channel Difference Rate reflects the consistency between analog switch channels. In a multiplexer, this parameter directly affects the signal quality.
Test method: By measuring the on-resistance of each channel, and calculating the ratio of the difference between the maximum and minimum values to the average value.
5. Implementation Suggestions
- Strictly control the test environment conditions: Ensure that the temperature, humidity and air pressure are within the standard range and avoid external interference.
- Choose appropriate test equipment: Including dual-trace oscilloscopes, precision current sources, etc. to ensure measurement accuracy.
- Follow the test procedures: Strictly follow the steps specified in the standard, especially in the test of multiplexers, which requires verification one by one.
- Record and analyze data: Create a complete test report, and perform statistical analysis on the results to identify potential problems.
