The measurement of points A, B, and C in Figure 2 determine the gain and phase of the control loop at the injection frequency (f). Different injection frequencies yield different gain and phase. For simplicity, and to see how this works, one can set the injection frequency and me...
The low-pass filters provide a path for low frequency power (DC to a few hundred Hz) to the DUT. The high-pass filters are used to measure supply and return supply line noise. These voltages are measured across 50 Ω resistors, as illustrated in Figure 5 and Figure 6.1 In a real...
which looks like a 15 uH inductance at its operating point. Staying under 15 uH is a squeeze, but this one seems to be a good start: -75 dB at 100 kHz when I put in some reasonable figures for ESR and DCR
Current flows through the resistors are wasted energy of I^2 R which converted to heat. To make all those resistors negligible, an inductor is added. With PMOS switching ON and OFF at a frequency f, the inductor L1, will have an impedance of j 2𝝅f L1 which is much higher than the...
Is that possible to measure continuous value..??? As you said it has a Max. Voltage of 30V and Current of 15mA. Is that possible to operate it with the 50kHz clock frequency..? coz in the Alter circuit board we have clock signal of 50MHz. Regards, Navin R ...
Simulation 1: Sources for Noise Analysis in the Frequency Domain In a noise analysis, LTspice uses all the noise sources it finds in circuit components such as resistors, transistors, and op-amps. This is sufficient for many analysis tasks, but sometimes a separate, independent noise sourc...
Ripple rejection- apply some ripple on the input at the desired frequency and observe how much gets through to the output. Drop-out- observe the output behavior as the input is increased from zero to a voltage a few volts above the output, with various loads. You can measure qui...
In LTspice, I-V data can be measured using the.DCSPICE command/directive. The ground clamp of DOUT1 is measured using the setup in Figure 4. In the setup, appropriate supply voltages were applied to configure the device in a high impedance state (please refer to ...
