Abstract
A square wave oscillator includes a Schmitt Trigger with a first output that outputs a first output current, a capacitor connected to the first output of the Schmitt Trigger, and a resistor that connects the capacitor to an input of the Schmitt Trigger to form a closed-loop negative feedback. The closed-loop negative feedback sustains an oscillation of the square wave oscillator and causes a frequency and an amplitude of the oscillation to be independent of a supply voltage of the Schmitt Trigger.
