Fundamentals of Semiconductors: Continuation on MOSFET Threshold Voltage

Continuing from the previous article on MOSFETs, this one will still take the enhanced NMOS as an example. We know that NMOS operates in several regions: cutoff region, linear region, saturation region, and breakdown region. The operating current of the MOSFET is related to the threshold voltage Vth. So, what parameters are related to the … Read more

How to Measure the Health of a MOSFET with a Multimeter

Use the unidirectional conduction characteristics of the parasitic diode inside the MOSFET to determine its health. Step 1: Short-Circuit the Three Pins for Discharge The purpose of this step is to discharge the parasitic capacitance inside the MOSFET to prevent any voltage difference, which could cause erroneous measurements. Step 2: Measure the Internal Diode Set … Read more

Five Solutions for Level Conversion Between 5.5V and 3V in UART Communication

In embedded systems, when communication is required between microcontrollers with different supply voltages, or between a microcontroller and peripheral chips operating at different voltages, level conversion is unavoidable. Otherwise, communication may fail, or the voltage may exceed the microcontroller’s tolerance, causing damage. Below are five mainstream level conversion solutions. 1. Resistor Divider Solution As shown … Read more

Why SPI Does Not Require Pull-Up Resistors

Hello everyone, I am Remember Cheng.I previously wrote an article:Why I2C Requires Pull-Up ResistorsI2C requires pull-up resistors due to its open-drain structure, which cannot output a high level, so external pull-up resistors must be added.When using SPI, we find that pull-up resistors are not needed. This is mainly because SPI typically uses a push-pull structure, … Read more
