## Determining width and length from CMOS inverter layout

How do I determine the width and length from the following cmos inverter layout, given that lambda=0.25um? The answer is Wn=1.0um, Ln=0.25um, Wp=0.5um, and Lp=0.25um. I know that the length is equal to 2 x lambda, but I do not understand how to get width from the layout.

## Can I connect a PSU to the Ramps 1.6+ and the USB to Arduino at the same time?

I just want to connect the Ramps to the power supply unit and upload the Marlin firmware to the Arduino. I found three possible outcomes 1. Problem I found one person here who says that we should not use external power for the Ramps and plug the USB to the Arduino at the same time […]

## What does “2 digit BCD number” mean?

When I read it, I think a 2 digit BCD number is something between 0 and 99 in decimal. So, for example, 0100 1001 is a 2 digit BCD number and decimal equivalent of it is 49 in my opinion. However, this question confused me. I want to interpret A_0 or A_1 as a 4 […]

## How To Play Music On PAM8610 With Esp32?

i’m trying to use xtronical’s DAC audio library on an esp32 to run 10W speakers. The board that xtronical used is a PAM8403 which has a signal voltage range of -0.3V to +0.3V but as it can only run 3W speakers thus i cannot use it. Hence, i am using a PAM8610 which can drive […]
