Triangular wave generator circuits are used in many modem circuit applications. Examples of these are applications in which a pulse width modulator circuit is used, such as in switching power supplies and induction motor control circuits. In this article a circuit is described for generating a quality trian- gular wave, with an amplitude determined by the power supply voltage and a resistor divider network, and at a frequency which is locked to a precision crystal oscillator.
