Oscillators with other waveforms ( 18 ) :

• 20MHz Function Generator - This compact function generator provides sine, square and triangular waveforms up to 20MHz over three ranges using "course" and "fine" frequency adjustment controls. The output level is adjustable from 0 to 2Vp-p. A TTL output is also provided for connection to a frequency counter.   
• Audio Oscillator 150 Hz - 150 kHz - This is an ICL8038 based function generator that gives out square wave, saw wave and sine wave outputs.   
• AVR Signal Generator - An audio signal generator and sweep generator with wide range, high accuracy and great versatility.   
• DDS device produces sawtooth waveform - Ramp or sawtooth waveforms are useful for a broad range of applications, including automatic-test equipment, benchtest equipment, and actuator control.   
• Function Generator - Built around a single 8038 waveform generator IC, this circuit produces sine, square or triangle waves from 20Hz to 200kHz in four switched ranges.   
• G�n�rateur de fonction 0.1 Hz - 10 Mhz - funacion generator 0.1 Hz - 10 MHz, based on MAX038, text in French   
• Low Cost Function Generator - low-cost function generator, based on the Maxim MAX038 high-frequency waveform generator, produces sine, triangle, and square waves from under 1 Hz to over 20 MHz   
• Oscillators convert temperature to time - simple arrangement of active-R oscillators can generate an excellent triangular waveform   
• Programmable ramp generator has 14-bit linearity - this linear ramp generator uses a DAC, a transistor array, MOSFET switches, and current-steering techniques to achieve 14-bit linearity   
• Scheme yields frequency-locked triangle waves - circuit generates frequency-locked triangle waves of constant amplitude, uses readily available TTL and other older-technology parts   
• SCR Oscillator - Silicon controlled rectifiers (SCR) can easily oscillate if there is an inductor (a speaker coil in this case) which gives just enough extra voltage to completely switch off the sustain current. In this way a new cycle may start and oscillations set in. It operates over a wide range of supply voltage and components values are not critical at all. Operational frequency in this circuit goes from 100Hz at 11V to 10KHz at 100V.   
• Summer linearizes ramp and triangle generators - op-amp adder that sums a reference voltage with the voltage on C1 allows the ramp generator and the triangle-wave generator to charge capacitor linearly   
• Triangle and Squarewave Generator - uses common 1458 dual op-amp   
• Tri-Waveform Generator - signal generator to test circuits, frequecy range is 20 to 20 kHz, outpus sinewave, triangle wave and square wave   
• Versatile Waveform Generator Operates from 0.1Hz to 20MHz - a single-chip source of high-frequency waveforms, the MAX038 can serve both as the core of a moderate-performance waveform generator, and as a card-level waveform source for electronic systems   
• Waveform Conversions: Sine to Square and Square to Sine   
• Waveform generator circuits - ramp generator, phase oscillator, quadrature sine/cosine oscillator   
• Operation explanation of the sawtooth wave oscillator
