Analog/RF and Mixed-Signal Circuit Systematic Design

Although within the electronic area, designers can take complete merits of IPs and layout automation instruments to synthesize and layout very complicated structures, the analog designers’ activity remains to be regarded as a ‘handcraft’, bulky and extremely time eating technique. hence, great efforts are being deployed to increase new layout methodologies within the analog/RF and mixed-signal domain names.

Solder Paste in Electronics Packaging: Technology and Applications in Surface Mount, Hybrid Circuits, and Component Assembly

One of many most powerful developments within the layout and manufacture of contemporary electronics programs and assemblies is the usage of floor mount expertise instead for through-hole tech­ nology. The mounting of digital units and parts onto the skin of a broadcast wiring board or different substrate bargains many benefits over putting the leads of units or elements into holes.

Sample text

We’ll start our study, this chapter, with a brief recap of the ideas we covered in the last chapter. We saw then that resistors in series may be considered as a single equivalent resistor, whose resistance is found by adding together the resistance of each resistor. This is called the law of series resistors, which is given mathematically by: Similarly, there is a law of parallel resistors, by which the single equivalent resistance of a number of resistors connected in parallel is given by: Using these two laws many involved circuits may be broken down, step by step, into an equivalent circuit consisting of only one equivalent resistor.

Not end-to-end as series joined resistors are, but joined at both 44 On the boards ends. We say resistors joined together at both ends are in parallel. 8 shows a breadboard layout. Both these resistors are, again, 10 k resistors. What do you think the overall resistance will be? It’s certainly not 20 k! Measure it yourself using your multi-meter and breadboard. You should find that the overall resistance is 5 k. Odd, eh? Replace the two 10 k resistors with resistors of different value say, two 150 Ω resistors (brown, green, brown).

What is the overall resistance? You should find it’s about 1k3 — neither one thing nor the other! So, what’s the relationship? Well, a clue to the relationship between parallel resistors comes from the fact that, in a funny sort of way, parallel is the inverse of series. So if we inverted the formula for series resistors we saw earlier: 46 On the boards we would get: and this is the formula for parallel resistors. Let’s try it out on the resistors of this last experiment. Putting in the values, 10 k and 1k5 we get: which is about 1k3, the measured value.
