The combination of .meas and .step statements enables the user to add a voltage noise source at the LDO input, and measure the LDO PSRR over a stepped change in voltage input over frequency. .meas Statements This allows the user to measure the peak-to-peak value of a signal over a ...
Fixes on the unittests after the spicelib update to 1.0.4 Version 5.2.1 Correction on the run_montecarlo.py and run_worst_case.py examples. Fixes on the spicelib (Version 1.0.3) Version 5.2 SimAnalysis supporting both Qspice and LTSpice logfiles. ...
For this simulation, we’ll provide a fixed input voltage of 250 mV, and we’ll use a “step” directive to vary the load from 1 Ω to 1000 Ω in 10 Ω steps. A“measure” directive allows us to plot error versus the stepped parameter (i.e., the load resistance) rather tha...
这一讲我们仿真噪声,这一版本的LTspice的help使用了网页的形式展现,这样更加便于翻译软件的大展身手。 翻译后的Noise说明如下: This is a frequency domain analysis that computes the noise due to Johnson, shot and flicker noise. The output data is noise spectral density per unit square root bandwidth.这...
