What is an Integrated Circuit (IC)?
An integrated circuit (IC) is a circuit in which components such as diodes, transistors, resistors, capacitors, and so forth are automatically made part of a small semiconductor chip. In other words, an IC is a complete electronic circuit in which both active and passive components are assembled on a small chip of silicon. When we…

Electronic IC Temperature Sensors
Electronic IC temperature sensors are specialized integrated circuits that are used for sensing temperatures in the -55° C to +150°C range. Basic Principle of IC Temperature Sensors The working principle of IC temperature sensors is based on semiconductor physics. When the temperature of a p-n semiconductor junction changes, the mobility of the charge carriers in…

Multiplexers and Demultiplexers in Digital Circuits
Multiplexers and demultiplexers are devices that route signals. A multiplexer also called a data selector takes one of several inputs and connects it to a single output. The input line that is connected is determined by the binary applied to the address lines. The diagram below shows a multiplexer with four input lines: The two…
