Analog / Digital IC Design

Digital IC Design

Digital IC design is a very complex type of design that is used in the creation of components such as microprocessors, different types of memory (RAM, ROM, Flash), digital ASICs, and FPGAs. The primary focus for an individual that is using digital IC design is on three things. The first is logical correctness. The second is circuit density. The more that can be added to a single circuit, the stronger the chip is going to be. The final thing that an engineer looks at is the placement of the circuits so that the clock and timing systems are as efficient as possible.

Analog IC Design

Analog IC design is a more basic type of design used to create op-amps, oscillators, active fillers, phase locked loops and liner regulators. Unlike digital IC design which is focused on fitting the most into the circuit as possible, analog IC design focuses on the physics of the semiconductor. The big things a designer pays attention to is the gain, matching, power dissipation and resistance of the semiconductor. Typically, an analog IC design uses a much larger area that a digital IC design. More so, they are typically less dense than digital IC designs because they are not about packing as much circuitry in.
In the end, despite what type of design – digital or analog – is being used is irrelevant. The process is the same. A computer engineer is trying to create electrical components on a piece of semiconductor such as silicon.

    Brilliant post. I think there is a gap in the market for this type of equipment, but this company are really filling the brief.

Integrated circuits

Integrated Circuits play a very important part in electronics. Most are specially made for a specific task and contain up to thousands of transistors, diodes and resistors. Special purposes IC's such as audio-amplifiers, FM radios, logic blocks, regulators and even a whole micro computers in the form of a micro controller can be fitted inside a tiny package.  Some of the simple Integrated Circuits         Depending on the way they are manufactured, integrated circuits can be divided into two groups: hybrid and monolithic. Hybrid circuits have been around longer. If a transistor is opened, the crystal inside is very small. This means a transistor doesn't take up very much space and many of them can be fitted into a single Integrated Circuit The pin-out for some of the common packages is shown Most integrated Circuits are in a DIL package - Dual In Line, meaning there are two rows of pins. (DIL16 and DIL8 are sh

How Does an Integrated Circuit Work

Integrated circuits are in almost every appliance known to man at this point in history from wristwatches to televisions and from coffee makers to, the most obvious, computers. An integrated circuit is a collection of diodes, transistors and microprocessors in miniature scale all operating on a single piece of semiconductor, typically silicon. Each performs a specific function that, when combined with the other components, can perform multiple tasks and calculations. First are the diodes; diodes by definition are electronic or electrical devices that regulate the flow or current of electricity within the circuit. Diodes control how much, when and how often electrons or electricity is allowed to flow into other parts of the system.We have all heard of transistor radios from the early 20th century and the transistors in integrated circuits, or ICs, are them same, at least by definition. Transistors can store voltage to stabilize the circuit or for amplifying a signal.

Merits or Advantages of Integrated Circuits

The integrated circuits offer a number of advantages over those made by interconnecting discrete components. These are summarized as follows     Extremely small size—thousands times smaller than discrete circuit. It is because of fabrication of various circuit elements in a single chip of semi-conductor material Very small weight owing to miniaturized circuit Very low cost because of simultaneous production of hundreds of similar circuits on a small semiconductor wafer. Owing to mass production an IC costs as much as an individual transistor     More reliable because of elimination of soldered joints and need for fewer inter-connections Low power consumption because of their smaller size Easy replacement as it is more economical to replace them than to repair them Increased operating speeds because of absence of parasitic capacitance effect Close matching of components and temperature coefficients because of bulk produc¬tion in batches Improved functiona
