This is the circuit of waveform generator. Waveform generator is very useful in electronic experiment and design. This circuit is generates sine wave oscillation, but actually we can modify the circuit to generate triangle or square wave function. This is the figure of the circuit.
This circuit is based on MAXIM IC. This integrated circuit chip gives complete function to build a waveform generator/function generator. Here some of modifications that can be used to build a complete waveform generator circuit:
· The circuit can be used to generate square wave, triangle, or sine wave by programming the pin inputs (A0: pin 3, A1:pin 4).
o A0 A1 WAVEFORM
o X 1 Sine wave
o 0 0 Square wave
o 1 0 Triangle wave
· The frequency can be controlled using current. If we disconnect the 20k RIN from REF (pin 1) and connect it to a DAC, then we can control the frequency using microcontroller or digital interface. We can even control the chip using a quartz crystal (PLL) by controlling the current using a phase comparator output that compares the sync output (pin 14 of MAX038) and a reference clock from quartz crystal oscillator.
