Practical circuit design and simulation tips to be used in DC Biasing, LDO/BGR, ADC Opamp design.

This course addresses those topics which are practical in nature and used by practicing engineers. The 3-hour course material is based on my CMOS Analog IC Design Q&A Refresher Course offered in Spring 2020, where practicing designers from the industry and academia brought out questions that they needed answers for.

There might not be a continuity of topics. I will try to cover the topics with in the scope of designing an ADC. These principles are applicable to most of the ADC designs.
