Guide Sawtooth-shaped oscillation from op-amp buffer?
near perfect sawtooth-shaped oscillation of perhaps 10-20 mV, frequency maybe 30 kHz (which is not visible on the input). Varying the resistors and/or output cap, shifts the oscillation in size and frequency. I''m no op-amp guru, does this sound like a pole in the transfer-function ? Shouldn''t that give a nice sine-wave ? Why the perfect saw-tooth?

3. You can use the 555 chip to generate a sawtooth waveform, instead of the square wave available from output pin 3. One way to do this is to drive the capacitor with a current source (which will give a linear capacitor voltage with time) and to reset the capacitor (discharge it) with the 555 discharge connection.

6 Frequently Asked Questions about “Why is the sawtooth wave a capacitor ”
How does a sawtooth waveform work in a capacitor charging circuit?
The cycle is repeated continually generating a sawtooth waveform across capacitor C. The resulting waveforms of capacitor voltage v C is shown in Fig. 30.132. The frequency of the output sawtooth wave can he varied by varying the value of resistor R E as it controls the time constant (T = R E C) of the capacitor charging circuit.
How does a sawtooth capacitor work?
The resulting current through the external resistor R develops a voltage spike and the capacitor voltage drops to the value V v. The device then cuts off and the capacitor commences charging again. The cycle is repeated continually generating a sawtooth waveform across capacitor C.
How does a sawtooth wave form?
There are several ways to generate sawtooth waves in electronic circuits: An integrator circuit linearly ramps up the voltage until it reaches a threshold. The output then rapidly discharges back to the starting level. Repeating this charge-discharge cycle produces a sawtooth waveform.
How does a sawtooth voltage generator work?
This sawtooth voltage generator circuit uses a four-layer diode as a switch. As soon as the capacitor voltage attains a specified value (10 V in this case), the diode breaks over and the latch closes. This discharges the capacitor, producing the flyback (sudden drop) of the capacitor voltage.
What is a fixed frequency sawtooth wave?
A fixed-frequency sawtooth wave is compared to an adjustable DC reference voltage. The comparator output generates a variable duty cycle rectangle wave that switches the motor windings. The sawtooth gradient, reference level, and PWM frequency determine the motor speed, torque, and efficiency.
What is a sawtooth wave in an oscilloscope?
In oscilloscopes, signal generators, and other test equipment, sawtooth waves serve as linear time base signals. The sawtooth waveform is applied to the horizontal deflection system to sweep the electron beam or sampling circuitry across the screen. Oscilloscope timebase generators must have excellent linearity and stability.
