關於運算放大器，
請告知CMOS運算放大器和雙極型運算放大器的不同之處。
- CMOS運算放大器具有極小輸入偏移電流（pA級）和低耗電量的特點。CMOS工藝的耐壓低，適於低電源電壓的應用。雖然雙極型運算放大器的輸入偏移電流、消耗電流比CMOS運算放大器多，但其具有易於提高耐壓、低雜訊、低偏移、寬頻帶的特點。

Is it a problem to Pullup the SCL and SDA lines of the I²C interface to 3.3V if DVDD=1.8V?
- 3.3V as the pull up source is acceptable even if DVDD is 1.8V. But NVCC_I2C of the I²C domain in SoC should be 3.3V (the same voltage as the pull up source for PMIC) and DVDD in PMIC always needs to be 1.8V.
