Electronic circuit engineer recruitment

1, the diode is a diode with two stages and unidirectional conduction, BJT is a current-driven transistor controlled by current, and MOS is a voltage-controlled transistor controlled by voltage.

2. The basic analog amplifier circuit is triode amplifier circuit. Just look it up online.

3.OCT and OCL are complementary and symmetrical power amplifier circuits, which can reduce the output resistance and improve the load capacity. The two circuits are different.

4. Capacitors can be divided into polar capacitors and nonpolar capacitors. The former is marked with positive and negative poles, while the latter is nonpolar.

5. Resistors can be classified in different ways. According to materials, there are carbon film resistors, cement resistors, metal film resistors and wire-wound resistors. According to the power, there are resistors with rated power such as 0.25W, 0.5W, 1W and 2 W, and according to the accuracy of the resistors, there are 5%, 10% and 20.

The above is a general answer, and the specific details should be viewed separately.
