The ADC internal design is based on the switched-capacitor technique. The following figures (Figure 1 to Figure 6) explain the principle of ADC operation. The example given below shows only the first steps of approximation but the process continues until the LSB is reached. Figure 1. ...
The cutoff frequency is inversely proportional to the product of the coupling capacitance and the resistance of the spectrum analyzer's input terminal. Since the impedance of the spectrum analyzer is a fixed value, usually 50 Ω, the capacitance of the AC-coupling capacitor determines how low of...
Another pitfall of AC coupling the TIA is the repetition rate of your laser source. When you AC couple the incoming pulses, the pulses will be averaged on the AC cap. The detector’s signal is unipolar and will slowly charge the AC capacitor. There will be a DC offset produced on this...
This AC-coupling capacitor will have a value of 0.033 μF when the device is running in 4-Gbps mode. At lower data rates, a larger coupling cap will be required. When connecting to a coax cable, the AC-coupling cap on the dummy side of the output (DOUTN) should also have an AC-...
Place the lowest-value capacitor closest to the power supply Key takeaways: You can achieve critical damping by adding a series damping resistor near the source, calculated using an RLC model. Implement series, and parallel termination methods to match signal line impedance and nullify reflected sig...
The choice of capacitanee in the circuitUsually audio circuits including filtering, coupling, bypass, scale and capacity, and how to more effectively in the circuit choose to use different types of capacitor to sound quality improveme nt has great in flue nee.1 35、. The filter capacitorAfter...
The resistor R3 will have a constant value of 1 MΩ to minimize the current through this resistor into the op amp. Taking the nearest standard capacitor value to have approximately a cutoff frequency of 20 Hz, let’s set C3 = 1.5 µF, so, the updated cutoff frequency is: ...
Bits 21:16 HSETRIM[5:0]: HSE32 clock trimming These bits provide user-programmable capacitor trimming value. It can be programmed to adjust the HSE32 oscillator frequency. Bits 15:0 Reserved, must be kept at reset value. 1.5 HSE configuration parameters...
This rectified line voltage is stored in the primary storage capacitor, C2. Note that the primary and secondary sections of the supply are electrically isolated by the flyback transformer, L2, and the optically isolated coupler, Q4. While the secondary section is connected to ground at the ...
Ripple Control: Based on cost and performance, reasonably control the ripple to reduce the inductor loss and capacitor loss caused by the ripple. In conclusion, improving the efficiency of DC-DC converters requires comprehensive optimization in multiple aspects, including component selection, circuit des...
