LTspice can help you achieve this with its AC analysis function. This video shows you how to perform a basic AC analysis in LTspice and highlights some lesser-known useful features.LTspice: AC Analysis LTspice: Stability of Op Amp Circuits LTspice: Noise Simulations LTspice: SAR ADC ...
Now we move over to the time domain and transient analysis. In the time domain, we need to produce the “fuzzy” waveforms we call noise. The sources shown here produce anapproximationof “white” noise. We will take a “deep dive” into the pseudo-random functions in LTspice a...
The Bode plots generated in LTspice can be compared to network analyzer Bode plot measurement results. Just like the simulation, the actual loop measurements are captured by injecting noise into the feedback loop and measuring and processing the A-B and A-C gain and phase. The measurem...
But if I want to build this and test it out with a function generator and scope, it's going to load a 50 ohm source in the place of V1 too much to get a clear picture of the transfer function. How can I characterize this circuit if I build it? The filter's input impedance will...
2. When considering the total supply current for the circuit, the choice of resistor values R1 and R2 also matters. The resistor choice is a trade-off between noise and power dissipation. In the case of this circuit, it is better to choose larger resistor values to minimize additional supply...
The smaller capacitance also helps the shot noise of the APD since they are proportional to one another. Sensitivity, bandwidth, and power must be balanced for real-world applications. Another challenge of having higher gains in the receive signal chain is the large dynamic range that comes with...
0.01 Hz as shown in Figure 2. It should be noted that the piezo sensor is significantly more expensive and, as expected, has a better noise performance from just under 0.1 Hz upward, but below this, the MEMS sensor has better noise performance down to 0.01 Hz and on to 0 Hz. T...
