WebThe switch model allows an almost ideal switch to be described in ngspice. The switch is not quite ideal, in that the resistance can not change from 0 to infinity, but must always have a finite positive value. By proper selection of the on and off resistances, they can be effectively zero and infinity in comparison to other circuit elements. WebApr 30, 2015 · Design Example. Verify the circuit below if it can operate as a switch. Vdd and Vcc are both 5V. Consider 80% device CTR and the forward voltage of the diode is 1V. Figure 1. For Optocoupler operation as switch the collector-emitter voltage must be zero or just equal to the maximum saturation voltage specified in the datasheet.
