40Khz Precision Triangle Generator  This circuit generates a precision 40KHz triangle waveform . . . Hobby Circuit designed by David A. Johnson P.E.July, 2006 HighFidelity TriangleWave Generator Consumes Only 6 µA  16Oct03 EDN Design Ideas: ideal triangle waves involve infinite d2V/dt2, so highfidelity triangle waves entail very high bandwidths. Micropower circuits have fairly low bandwidth, so generating good triangle waves with such circuitry becomes problematic. The circuits of Figure 1 show two methods of generating triangle waves Design by Glen Brisebois, Linear Technology Corp, Milpitas, CA

Scheme yields Frequency Locked Triangle Waves  02/02/98 EDN Design ideas: The circuit in Figures 1 and 2 generates frequencylocked triangle waves of constant amplitude. it uses readily available TTL and other oldertechnology parts. The circuit portion in Figure 1 comprises the frequency dividers, counters, and converter. The portion in Figure 2 contains current sources, output circuits, Design by Daniel Dufresne, Decatron, St Bruno, PQ, Canada Summer Linearizes Ramp & Triangle Generator  12/08/94 EDN Design ideas: The ramp generator in Fig 1a and the trianglewave generator in Fig 1b charge capacitor C1 linearly. The key to the circuits' linearity is an opamp adder that sums a reference voltage with the voltage on C1. For Fig 1a's ramp generator, the adder comprises opamp IC 1, R4, R5, and associated components Design by Valery G Chkalov, Scientific Association "Typhoon," Obnisk, Russia 


Transconductance Amp Gives Oscillator Reciprocal Response  17Apr03 EDN Design Ideas: Highside current sensor monitors negative rail  The circuit in Figure 1 is a variation on the familiar integrator/comparator trianglewave oscillator, which you typically implement with two op amps. An integrator and a comparator connect in a positivefeedback loop; the comparator drives the integrator and vice versa. A fixed amount of hysteresis exists in the comparator, producing a triangle wave at the integrator's output Design by Mike Irwin, Shawville, PQ, Canada Triangle & Square Wave Generator  Here is a simple triangle/squarewave generator using a common 1458 dual opamp that can be used from very low frequencies to about 10 Khz. The time interval for one half cycle is about R*C and the outputs will supply about 10 milliamps of current. Triangle amplitude can __ Designed by Bill Bowden
Triangle / Square wave generator  Transistor Q1, a 2N3563, and its associated components form an oscillator circuit that will oscillate if, and only if, a good crystal is connected to the test clips. The output from the oscillator is then rectified by the 1N4148 signal diode and filtered by C3, a 100pF capacitor. __ Designed by Izhar Fareed
