Introduction
The following links contain macro models built for LTspice with the purpose of turning large-scale simulations into block-level schematics, similar to hierarchy design but with predefined models. The domains of interest include, but are not limited to, power electronics ([Pwr]), digital devices ([0101]), mathematics equations ([Math]), filtering and control theory ([Filt]). In addition, there is one more model, Filter, that is made to be a sort of a universal filter for LTspice. The links go to an external site, for now, until I fully merge all the pages to blend in with LTwiki. The lists describing the contents of every folder is limited to enumeration and a simple description, details are in the links.
This folder holds the following:
ADC16 |
an asynchronous (max) 16bit ADC |
Bin2Dec |
a binary to decimal translator |
CNT16asy |
an asynchronous (max) 16bit counter |
DAC16 |
a (max) 16bit DAC |
Dec2Bin |
a decimal to binary translator |
JKFLOP |
a behavioural JK flip-flop |
[Filt]
The contents of this folder is mixed filtering and control theory.
AGC |
an automatic gain controller w/out external frequency control |
DeadTime |
dead-time |
DeadZone |
dead-zone |
Delay |
analog -- exp(-sT) -- or digital -- z-1 -- delay
|
Diff |
differentiator |
FFT |
actually a continuous-time Fourier decomposition, but FFT is shorter
|
Filter |
a universal filter, separate |
FreqDet |
frequency detector |
Gain |
a linear/dB gain/buffer with variable output resistance |
Integ_r |
resettable integrator w/out external period control |
LeadLag, LeadLag2 |
two versions for a <-π..π> lead-lag control, w/out external control
|
Lim |
hard limitter |
MUX |
a simple externally controlled analog multiplexer |
PhaseDet |
phase detector |
PID |
a universal PID/PI/PD/ID/P/I/D analog/digital controller |
PLL |
a phase-locked loop with single/quadrature inputs |
SampledSource |
LTspice's own SINE and/or PULSE sources, sampled |
StateSpace |
1st/2nd/3rd order, SISO state-space block |
UpDnSpl |
.AC -friendly up-/down-sampler
