Single Ended vs Differential Inputs

Image
One of the most common questions asked is the difference between single-ended and differential signals inputs, and what applications they should be considered in. It is important to know the difference between single-ended and differential inputs as it can greatly affect the quality of your data Differential signaling  is a method for electrically transmitting information  using two complementary signals . The technique sends the same electrical signal as a  differential pair  of signals, each in its own conductor. The pair of conductors can be wires (typically twisted together) or traces on a circuit board. The receiving circuit responds to the electrical difference between the two signals, rather than the difference between a single wire and ground . The opposite technique is called single-ended signaling. A  single-ended input  measures the voltage difference between a wire and the ground. This difference is then amplified to provide the output. Single-e...

Clock Signal In Digital Circuits

Timing components are one of the most ubiquitous components in electronics. They are needed in nearly every complex design and all our electronics wouldn’t work without them.  In this article, I will be explaining the different kinds of timing components available and just why clocks are so important in digital electrical circuits. What is a clock signal? We can define a clock signal as a particular type of signal that oscillates between a high and a low state. The signal acts like a metronome, which the digital circuit follows in time to coordinate its sequence of actions. Digital circuits rely on clock signals to know when and how to execute the functions that are programmed. If the clock in design is like the heart of an animal, then clock signals are the heartbeats that keep the system in motion. How are the clock signals produced? There are different ways a clock signal can to be produced, but they all start off with the  crystal resonator .   A crystal resonator is ...
