Transistor as a switch, is the transistor working in the saturation zone, the NPN transistor as an example (all of the following) As shown in the figure: when the vin=0, transistor b-e There is no forward bias, and cutoff, equivalent to the state of disconnection, at this time vce=vcc,c pole current ic=0; When the transistor is closed (in the saturation zone), the load RC and transistor equivalent in series, through the RC current, through Ohm's Law,

. · Cluster NAS and horizontally scalable file systems. EMC isilon is directly competing with HP storeever. EMC isilon has become the company's rapidly growing product in recent years and has a leading market position in the cluster NAS field. · Object Storage Service (OSS). EMC atomos and HP storeall also have some market conflicts. · Integrated systems: VCE/vspex directly competes with HP converged systems.

ensure that the transistor must be in the cutoff state.2, enter the saturation zone condition: First collector to be connected to a load resistor R1, the base to be connected to a base resistor R2, as shown in figure. 1. To transmit the current to the load, the transistor collector and emitter must be shorted. It is therefore necessary to have VIN reach a sufficiently high potential to drive the transistor into the saturated working area. When the transistor is saturated, the collector current

click on the Simulation toolbar to run the simulation. This brings up the PSpice interface. By selecting View/output file, 1-28, you can open files that store the static work point simulation results. 1-29, the amplifier determines the static operating point of the main observation transistor VCEQ,IBQ and ICQ three values, the appropriate static operating point needs to be located in the transistor output characteristic curve of the amplification area, preferably close to the middle of the AC l

1. How to determine whether a basic amplification circuit is a common-base, co-injection or a common set? Remove the input, the output side, the rest is the common end. The following figure: The UI is connected to the base pole, and the UO is the common collector. 2. Basic Amplification Circuit: 2-1. Co-emitting minimal signal amplifier Function: Amplify the small amplitude voltage signal Working principle: Q1 is connected to the common-injection configuration single-tube amplifier, R1,R2 pr

general circuit to meet these three requirements. The circuit diagram is as follows: Figure 1 driving circuit For NMOS 2 driving circuit for PMOS Here I will only make a simple analysis on the NMOS drive circuit: The two voltages can be the same, but the VL value should not exceed. Q1 and Q2 form an inverted totem bar to achieve isolation, while ensuring that the two drive tubes Q3 and Q4 do not turn on at the same time. R2 and R3 provide the PWM Voltage Reference. By changing this reference, t

around the integration infrastructure, but only to a different degree. The first solution is typically a data center rack: Companies involved in virtualization combine to create a pre-built and tested hardware platform that is supported by a single vendor. The most famous of these solutions may be the Vblock provided by Cisco, EMC, and VMware, but other companies have taken action, as Dell offers Vstart solutions. Users need to buy only the infrastr

this technology. As an IT technology manager for a Nasdaq-listed U.S. company in China, I am also responsible for the infrastructure and data center design of the Chinese factory. Last year (2013), we deployed flexpod. This is a unified computing architecture jointly launched by Cisco, netapp, and VMWare, it cleverly uses the Cisco UCS technology to strip all server configurations and place them in the configuration file, making the server a pure box that provides computing and memory resources

Analog Circuit-like valve semi-pass control of its startup determines the power consumption of the water stream without signal when the water flow is working The digital circuit valve is in or off two States. When the valve is completely closed, there is no power consumption. I am sure I know some principles about the descriptions of the full and cut-off areas. Let me modify the analogy: Closing area: the closing area should be able to open the valve. Full zone: the valve should be opened too.

the transistor is turned on), The D5V0 (5 V High) is directly added to the CE level of the transistor, And the CE level of the transistor is easily damaged. Further analyze its working mechanism: When the input is high, the transistor is turned on, and the output is clamped at the Vce of the transistor, the circuit test result is only 0.1 V. When the input is low and the transistor is not turned on, the output is equivalent to pulling up the inpu
