Description: 
"This astable oscillator circuit uses CMOS inverters made out of discrete MOSFETS. Regular EWB gates may not simulate as they are \"idealized\" to make them simulate faster. The time-delay switch has been added to \"jog\" the circuit into oscillations by quickly charging the capacitor. The transistor is driven from the output of the gate and is used as a switch to control the LED.."
