While theNet Sectionfor VDD defines the parasitic RC network and its connectivity, the design instance cells (MOSFETs, resistors, subcircuits, etc.) with width, length, and other parameters can be found in theInstance Sectionof the DSPF file. Spectre usage of DSPF...
When rotating, the encoders modulate a beam of light whose intensity is sensed by photo-electrical cells, producing two 90° (el.) phase-shifted sinusoidal signals A and B. B lags A with clockwise rotation viewed from the shaft side of the encoder. The number of periods of A and B ...
