If a buck converter is operating at FPWM continuous mode, will it still operate if the load current is low in which it can enter discontinuous mode?
Usually we design the inductor needed to be 1/3 of the Iload max in order to have a good trade off between eff and transient response. If i...
I want to use a speciifc notch filter using a tank circuit from input to output(series). If I wanted to tune the tank using varactor, back to back diodes, how can I connect the positive polarity of my supply assuming I connect the neg polarity at the middle on back to back diodes(reverse)...
If changing the DC/ave load current of the buck converter, does it affect output ripple? Why or why not??
I measured and it doesnt affect the output ripple of a buck converter with changing load current(not ripple current)..please give the best explanantion.
which one is preferred method on measuring output ripple fo switchers, output capacitor probed with a 50ohm coaxial terminated at the scope of 50ohm or using with 10:1 oscilloscope probe with 1M input termination(tip and barrel method)?
I saw one article that measuring outout ripple should...
is there anyone who have successfully measured AC PSRR of LDO using Hittite LDO microwave? I have a science project and i wish to measure its psrr. Is the input capacitor should be included when measuring PSRR?
I want to measure a certain AC signal riding on a DC in a powered up LDO. Purpose is measuring PSRR. Can an external DC blocker be effective in eliminating loading effect to the ckt since Im only using a BNC coaxial cable(1x) at 50 ohm termination?
Will this be the same with the 10x passive...
I need the advantage and disadvantage of having a large output capacitor and inductor in a buck converter. What I know is having a large output capacitor decreases output ripple and the having a large inductor decreases inductor current ripple and turns to decrease output ripple as...
Do anyone know the concept behind resonant regulators? I think this uses resonant frequency at its operating frequency. Any links or products in the market which uses this concepts?
hello guys, have anyone of you encountered or experiment a ripple injected in power supply rail which modulates to the fundamental (analog IN) in the FFT spectrum of an ADC. Sample is 2Mhz injected ripple, fundamental 30M produces 26M, 28M, 32M and 34M lower amplitude spurs in FFT spectrum. it...
Just want to confirm if the purpose of averaging in acquisition mode in a oscilloscpe is to average the absolute signal and remove the apparent and random noise. Is it applicable or right to use averaging in an oscilloscope in measuring very low level ripple in a DC/DC converter?
Do anyone have the chance to measure the low noise output of LTC1533 (100uV peak to peak)? I tried measuring the low noise output of this part and it seems I'm getting 5x worse--500uV peak to peak. I appreciate anybody's help.
Here's the link I'm pertaining...
I was thinking to use a 50 ohm input set in scope with a 50ohm BNC coaxial cable in measuring a voltage ripple from an output capacitor of a buck converter. The output voltage is 1.8v with a dummy resistor load of 3.7ohms. The BNC coaxial cable is properly terminated in scope input, will...
