It usually requires a negative supply as sketched in Figure 1, where Vsaw = -(-V) Tsq/(R1C1). Figure 1 The usual topology for converting digital square waves to analog sawtooth requires a negative ...

a near cousin of the square wave above. What’s making all this work for us? Some dead-boring amplification with negative feedback, and the (mis-)use of a logic chip to get it. After the break I ...

A simple description of the operation of the circuit: An ultra-fast one-shot is forced by negative feedback to produce a 50% duty cycle square wave output. I added a 50-ohm termination and a ...

This very-low-frequency sine- and square-wave generator requires few components ... outputs from this simple generator (d). A possible negative aspect of this circuit is that it requires a ...

That’s because a real square wave goes in equal amounts positive and negative. So a 5 V square wave, for example, is always at either 5 V or -5 V and, either way, the same amount of work gets done.
