Beyond SPICE – Analog/Mixed Signal Simulation

13/08/2019, hardwarebee

Many electronics developers are very familiar in doing circuit simulation using SPICE (Simulation Program with Integrated Circuit Emphasis) models, netlist and a SPICE simulator tool. There are quite some tools in the market, even some of them free of charge. In this article, I like to inspire a

Introduction to RS-232 Standard

28/06/2019, hardwarebee

RS-232 stands for Recommendation Standard 232. Introduced in 1960 and used as serial ports in computer systems, the RS-232 is a set of standards that defines the characteristics and timing of the electrical signals that pass from the computer to the modem, as well as their meaning and size. The

Digital to Analog Converter Basics

Our world today is as dependent and centered on technology as it has never been before. Electronic products play a central role in ensuring that our daily life and the infrastructure we utilize are working optimally. You would not be able to operate your electronic gadgets if you did not

Introduction to Watchdog Timer

14/05/2019, hardwarebee

A watchdog timer is a piece of hardware that is constantly monitoring whether the processor is acting properly, and if it detects any anomalies it resets the processor. A watchdog timer is installed in almost every embedded system today, and it’s a mandatory solution especially in products whereas a human

Introduction to Power-on-Reset

12/05/2019, hardwarebee

A power-on-reset circuit is responsible for generating resetting signals whenever power is supplied to a given electrical device. In such manner, you can determine a known state in which the device always powers up or starts operating.
 

 
The risk in not having a power on reset signal

What is DC-DC Converter?

11/05/2019, hardwarebee

As the name suggests, a DC to DC Converter is meant to convert one DC voltage into another DC voltage. They are used to increase or decrease the voltage level. DC to DC converters are based on an electronic circuit that uses electronic switching technology. A DC to DC converter
