Hello, guys! I'm not sure how silver oxide 357 size button cell batteries compare to LR44 button cell alkalines in terms of run duration. (For example, in a Pelican L1). Is there a difference in time between silver oxide and alkaline? When I replaced the LR44s in my L1 with 357s, I saw a...

Hi, I have one doubt in am437x design that is in gigabit ethernet PHY chip design. As per the datasheet of KSZ9031RNXCA (PHY chip) AVDDl, DVD-DL, and AVDDL_PLL maximum voltage are 1.8V. But the design applied 3.3V through P channel Mosfet. I know it is working fine in EVM. Is there any...

Good day, everyone! I'm working on a design that starts with a standard Colpitts oscillator. As an example, consider the following: It works, but I'm not sure how to determine the values of the individual components. I've run several simulations and have a paper with numbers and results, but I'm...
