Notes/Equations
- Comparator outputs a 1V signal whenever the baseband portion of the input signal is between the two threshold voltages. Input impedance is infinite; output impedance is fixed at 0.1 Ohm; and, there is a fixed delay of one timestep.
- If the baseband portion of Vin is greater than Vlow and less than Vhigh, then the output voltage at the next time sample is 1.0V; otherwise, the output is 0.0V.
- This model works in transient and circuit envelope simulation.
