Printed circuit boardWikipedia

In informal usage, the term "printed circuit board" most commonly means "printed circuit assembly" (with components). The IPC preferred term for assembled boards is circuit card assembly (CCA), and for assembled backplanes it is backplane assemblies. "Card" is another widely used informal term for a "printed circuit assembly".

Classes of Power Amplifiers (Class A, B, AB, C, D

 · Class D amplifier is the highest power efficient amplifier class in the A, B, AB, and C and D segment. It has smaller heat dissipation, so small heatsink is needed. The circuit requires various switching components like MOSFETs which has low on resistance. It is a widely used topology in digital audio players or controlling the motors as well.


OPTOELECTRONICS CIRCUIT COLLECTION By Neil Albaugh AVALANCHE PHOTODIODE BIAS SUPPLY 1 Provides an output voltage of 0V to +80V for reverse biasing an avalanche photodiode to control its gain. This circuit can also be reconfigured to supply a 0V to –80V output. LINEAR TEC DRIVER–1 This is a bridge-tied load (BTL) linear amplifier for driving

How to Sell Circuit Boards for Scrap | It Still Works

The common collector or grounded collector configuration is commonly used where a high impedance input source needs to be connected to a low impedance output load requiring a high current gain. Consider the common collector amplifier circuit below. Common Collector Amplifier using an …

Diodes and TransistorsUniversity of California, Berkeley

are commonly used as diodes: electrical switches that allow a flow of electricity in one direction but not in the other (opposite) direction. This property is explained in terms of the forward-bias and reverse-bias effects, where the term bias refers to an application of electric voltage to the p-n junction.
