![]() Linear ICs are typically used in audio and radio frequency amplification. For example, a component on a linear IC may multiple an incoming value by a factor of 2.5 and output the result. The term "linear" is used since the output value is a linear function of the input. This means a component on a linear IC can take a value of any kind and output another value. ![]() Digital ICs are the kind you will usually find in computers, networking equipment, and most consumer electronics.Īnalog, or linear ICs work with continuous values. The transistor is the primary building block of all microchips, including your CPU (central processing unit). The picture shows several examples of transistors. A low signal sent to to a component on a digital IC will result in a value of 0, while a high signal creates a value of 1. It is a component used to control the amount of current or voltage or used for amplification/modulation or switching of an electronic signal. These extremely small electronics can perform calculations and store data using either digital or analog technology.ĭigital ICs use logic gates, which work only with values of ones and zeros. Noun Filter noun transistors A solid-state, electronic device, composed of semiconductor material, as germanium, silicon, etc., that controls current flow without use of a vacuum: transistors are similar in function to electron tubes, but have the advantages of being compact, long-lived, and low in power requirements. The transistor is a semiconductor device which transfers a weak signal from low resistance circuit to high resistance circuit. ![]() The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. An IC is a small wafer, usually made of silicon, that can hold anywhere from hundreds to millions of transistors, resistors, and capacitors. Central Processing Unit (CPU) Google Classroom. An integrated circuit, or IC, is small chip that can function as an amplifier, oscillator, timer, microprocessor, or even computer memory. They take power to do this, and the smaller the transistor, the less power is required.
