When looking at the oscilloscope feature of a multi-instrument device or when comparing two benchtop oscilloscopes, the first specifications that we look at are the bandwidth and sample rate. While these …
As February, Black History month, draws to a close, we want to highlight the achievements of an amazing and inspiring engineer. Astronaut Robert Lee Curbeam, Jr., was born in 1952 and is the astronaut who holds the record for most space walks on a single flight.
Welcome to the first expanded explanation post in our series on the ‘Components of an FPGA’. This post will describe the architecture of a configurable logic block (CLB) and the functionality this component serves within a field programmable gate array (FPGA).
Take a look at a circuit board and chances are you're going to find a resistor or two. Most boards today use surface-mount device (SMD) technology, so the components are almost too small to see sometimes, but they are on there, I promise. How do engineers decide which resistors to use in the design? Sometimes it depends on how you want that portion of the circuit to perform, as in the case of an op-amp. Other times it's to prevent too much current from passing through a given point in a circuit, which is why they are often called current-limiting resistors. Maybe you want a simple way to divide the voltage or current. The reality is that there are numerous ways to use resistors, and oftentimes, the defining the resistor value is up to you.
