1. Basic structure of NICEthernet card in the data link layer of the chip is generally referred to as a Mac controller, the physical layer of the chip we simply call PHY. Many network cards chip the MAC and PHY functions into a chip, such as the Intel 82559 network card and 3COM 3c905 network card. But the mechanisms of MAC and PHY exist separately, but the appearance is a single chip. Of course, there are a lot of network cards Mac and PHY are done separately, such as D-Link dfe-530tx and so on

Before using Multisim to do op amp circuit simulation found that op amp output is more than the phenomenon of power rails, and sometimes want to take the OP put when the comparator do open-loop simulation, but in the Multisim simulation is actually linear amplification, and output over the supply voltage, very depressed, so after simulation is used cadence The orcad/pspice to simulate.But draw a frequency response to use a formula to draw, the signal

You just need to click a check box in the auto-wiring settings.Q: How can different net in the pcb be c

stable working state. Next, we will analyze in detail the transition process of the switching power supply at the start time. In Figure 1-19, when the active switch is switched from power-on to power-off, the back-EMR generated by the secondary Coils of the switching power supply transformer is:In formula, Q is the charge volume stored by the capacitor, c1 and c2 are the undetermined coefficient, ω =, is the angle frequency, that is, the charge rate

devices, comparator, oscillator, pulse width modulation, reference voltage, and other circuits. This part of the circuit has been integrated, made into a variety of switching power supply integrated circuit. The control circuit is used to adjust the switching time ratio of the high-frequency switch component to achieve the goal of stable output voltage.2. Single-ended anti-excited switch power supplyThe typical circuit 3 of the single-ended anti-exciting switch power supply is shown in. The so-

The ing method returns a string, because it is assumed that the output is composed of character data. In addition, you can also use a StringBuffer.SQLMapper requires an SQL query string, an output type set, and a DataBaseHandler for executing specific work. They are initialized using the set method and retrieved using the get method:If (getSQL ()! = Null) (GetSQL ().

Sqlmapper The Sqlmapper class uses a Databasehandler class to complete its database work and uses a mapping method to convert the document object to the desired output type.

The data link layer provides addressing mechanisms, data frame construction, data error check, transfer control, and standard data interfaces to the network layer. The data link layer chip in an Ethernet Card is generally called a Mac controller, while the physical layer chip is called a Phy. Many Nic chips enable Mac and PHY functions as one c
