Features of integrated circuit components
1. The accuracy of a single component is not high, and it is also greatly affected by temperature. However, the performance of components manufactured by the same process on the same silicon chip is relatively consistent, the symmetry is good, and the temperature difference of adjacent components is small, so the same The temperature characteristics of similar components are basically the same;
2. The value range of integrated resistors and capacitors is narrow, and resistors and capacitors with larger values occupy a large area of silicon chip. The integrated resistance is generally in the range of tens of Ω to tens of kΩ, and the capacitance is generally tens of pF. Inductance cannot be integrated yet;
3. The absolute error of component performance parameters is relatively large, while the ratio of performance parameters of similar components is relatively accurate;
4. The vertical NPN tube has a large β value, which occupies a small area of the silicon chip and is easy to manufacture. The β value of the horizontal PNP tube is very small, but the withstand voltage of its PN junction is high.
