NMOS and diode based level shifter design

Introduce two different level shifter for logic circuit design: the NMOS-based design and the diode-based design. This blog will introduce the working principle of both design, provide PCB layout for both of them using SMD, provide timing diagrams using scope for both implementation, and compare the pros and cons of them.
