AC signal can be amplified as AC amplifier circuit. Common AC amplifier are: fixed bias type, voltage negative feedback, current negative feedback, negative feedback and 63 datasheet and hybrid twin-tube direct-coupled 5 kinds. in industrial automation and 63 price and wireless technologies, are often encountered in many signal is very weak, to thousands of times magnification, or even a million times or more to drive the lo...

Capacitors is to achieve a wide range of supply voltage and 60 datasheet and current combinations of one of the most critical passive components. While each of capacitors can store energy, but for specific applications, the capacitor dielectric technology selection plays an important role. capacitors in the power of the most important application is the storage of energy, surge protection, EMI suppression and 60 price and co...

Successive approximation type A / D from the comparator, D / A converter, comparator register SAR, clock generator and 65 datasheet and control logic circuit, it samples the input signal is continuously compared with the known voltage and 65 price and then converted into a binary number. shown in Figure 10-8, when the measured voltage Ux analog input to A / D, it first compares the reference voltage UR, the reference voltage...

Radio Frequency Identification RFID is the abbreviation, that is radio frequency identification, commonly known as RFID. RFID Radio Frequency Identification is a non-contact automatic identification technology, which RF signal automatic target recognition and FDC6401N datasheet and access to relevant data, identify the work without human intervention, can work in harsh environments. RFID technology can identify fast m...

Set a base reverse saturation current is due to the collector junction is reverse biased, collector-base region and 68 datasheet and the drift of minority carrier movement formed by the current, so it influenced by temperature. At room temperature, low-power germanium tube Iaro about a few microamps to tens of microamps, low-power silicon tube ICBO microamps or less. ICa0 the smaller the better temperature stabili...

Digital circuit design the basic principles of interference is: (1) sources of interference suppression, interference sources, such as loop through the series inductance or resistance and 67 datasheet and increase the freewheeling diode to achieve. (2) cut off the interference propagation paths, interference propagation path can be divided into two types of conduction and 67 price and radiation. The so-called conduction di...

(1) of the continuous signal such as the formation of the sampling interval sampling signal, sampling the signal spectrum is continuous spectrum with a sampling frequency of the signal cycle of the periodic extension form. (2) the signal of the highest cutoff frequency fi, the sampling frequency f2, if the sampling frequency f2 2fi, then let the sampling signal through a cut-off frequency fi of...

Data entry process, the data from a one peripheral interface into the receive shift register, when the receive shift register has been received a character of you, the data from the receive shift register into the data input register. CPU read from the data input register receives Yun characters. (Concurrent read, that D7 ~ DO also be read into the Accumulator). Receive shift register shift clock ...

PCB design is one of the regular practice in all key parts in the PCB configuration appropriate decoupling capacitors. Decoupling capacitors in a typical configuration principle is: (1) power supply input 10 ~ 100 vF across the electrolytic capacitor. If possible, take 100 t, F or more capacitor better. (2) in principle, each integrated circuit chip layout should be a 0. A pair of pF ceramic c...

ADC conversion characteristics determined mainly by the different conversion methods have different limits the number of bits, while the corresponding non-ideal characteristics of error mainly by the manufacturing process to guarantee. For example, the manufacture of integrated circuit 8-bit ADC requires the matching accuracy of its resistance is 0.05 percent. Heres integral, bit by bit more style...
