Which IC is used as waveform generator?

Which IC is used as waveform generator?

Waveform generator Examples are the Exar XR2206 and the Intersil ICL8038 integrated circuits, which can generate sine, square, triangle, ramp, and pulse waveforms at a voltage-controllable frequency.

Which of the opamp is used for generating triangular waveform?

A triangular wave generator is an electronic circuit, which generates a triangular wave. An operational amplifier based triangular waveform generator is a simple circuit that is widely used in function generators. The circuit for Triangular wave generator is designed using 741 op amp.

How do we get triangular wave with square wave generator?

A triangular wave is generated by alternatively charging and discharging a capacitor with a constant current.

1. This is obtained by connecting the integrator circuit at the output of the square wave generator.
2. Assume that V’ is high at +Vsat.

What is the difference between the Sawtoothwave and triangular wave?

The difference between the triangular and sawtooth waveform is that the rise time of the triangular wave is always equal to its fall time while in sawtooth wave generator, rise time may be much higher than its fall time or vice versa.

Which is generate sawtooth wave?

A sawtooth wave generator can be constructed using a transistor and a simple 555 timer IC, as shown in the below circuit diagram. It consists of a transistor, a capacitor, a Zener diode, resistors from a constant current source that are used to charge the capacitor.

What is a waveform generator used for?

Introduction. Waveform Generators are used to apply specified analog signals to circuits, anything from DC signals, sine waves of varying frequencies, AM/FM modulated signals, and more. This guide explains the use of the Waveform Generator instrument in WaveForms. This instrument is also referred to as the Wavegen.

What is the triangular wave generator?

A triangular wave generator is an electronic circuit, which generates a triangular wave. The block diagram of a triangular wave generator is shown in the following figure − The block diagram of a triangular wave generator contains mainly two blocks: a square wave generator and an integrator.

Which oscillator is also a triangular wave oscillator?

An integrator which converts square waves to triangular waves. The circuit uses an opamp based square wave generator for producing the square wave and an opamp based integrator for integrating the square wave. The circuit diagram is shown in the figure below.

What is square wave generator and triangular wave generator?

The block diagram of a triangular wave generator contains mainly two blocks: a square wave generator and an integrator. These two blocks are cascaded. That means, the output of square wave generator is applied as an input of integrator. Note that the integration of a square wave is nothing but a triangular wave.

How can you obtain triangular wave using Schmitt trigger?

When the output of Schmitt trigger is low, the integrator develops a rising ramp which increases till it reaches UTP, as illustrated in figure. At this point the output of the Schmitt Trigger switches to the high state and forces the triangular-wave to reverse in direction.

What is a triangular wave generator (max9000)?

The application circuit uses an op amp, comparator, and a voltage reference as active building blocks. The MAX9000 is chosen because it integrates these three components. The linearity of triangular waveforms makes triangular wave generators useful in many “sweep” circuits and test equipment.

What is a triangular wave generator used for?

The linearity of triangular waveforms makes triangular wave generators useful in many “sweep” circuits and test equipment. For example, switched-mode power supplies and induction motor-control circuits often use a triangular wave oscillator as part of the pulse width modulator (PWM) circuit.

What is a triangular wave oscillator?

For example, switched-mode power supplies and induction motor-control circuits often use a triangular wave oscillator as part of the pulse width modulator (PWM) circuit. This article presents a compact, triangular wave oscillator using a single MAX9000 IC and some passive components.

What is the voltage of a triangular wave?

To generate a triangular wave from 0.5V to 4.5V, for example, a reference voltage of (0.5V + 4.5V)/2 = 2.5V is needed. Since a standard bandgap reference has an output voltage of 1.23V, it would be preferable if the voltage range of the triangular wave could be set independent of the bandgap reference.
