  • Functional Safety of 4/20mA Networks

    •  Analog Employees 
    In my first blog of 2021, I will go back to a purely technical topic and discuss the functional safety of 4/20mA networks. I often make use of 4/20mA examples to explore functional safety questions due to their simplicity and the fact that...
  • How Functionally Safe Am I?

    •  Analog Employees 
    After a year of functional safety blogs, this is my last one of the year. It is a Christmas blog if you like. Similar to last Christmas this blog has a somewhat tenuous connection to functional safety but there is a connection. I like to imagine myse...
  • Radio Goes Back to Future

    When Lee de Forest invented the first electronic amplifier tube (the Audion) in 1906 the iconic inventor gave us the foundational invention needed to kick-start the development of long-distance telephone, radio, radar, and the first computers. Since ...
