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...
In a previous article, we discussed some examples ofmodeling noise in LTspice. Now, let's discuss how to build noise sources in the frequency domain using noise analysis and in the time domain using transient analysis. We'll do this by simulating circuit noise in LTspice. This article ...
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...

off Q1 and in turn Q2 ( and I think the other cap makes the short delay between the two ( where the cap is loaded) i would think the cp would become laded to more as 1V. Then current is higher as I thought or your led had a higher Vf ( i took 2V like most red leds are...
So amplitude is just a measure of the DC power supply level. The next parameter we can adjust is the frequency of the sinusodal waveforms. There will be a series of sine waves created by this circuit and we can adjust what frequency these signals will have by the selection of the inducto...
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 ...
