Direct digital synthesis ICs can convert square waves to sine/cosine waves but their complexity is a disadvantage. This circuit uses simple CMOS logic and two switched-capacitor filters to perform ...

The figure shows the schematic for the square-wave-to-sine-wave converter. A crystal and a 10-MO resistor are connected across pins 5 and 6 of the RDD104. A 100-pF capacitor (C5) is tied to pin 5.

Med Dyer, Jabra Corp, San Diego, CAGenerating a square wave at a particular frequency is fairly simple. Many techniques for doing so exist, using counters, flip-flops, and–everyone's favorite–the ...

Simple sine-wave generators can offer varying degrees of performance, but you’ll find it difficult to maintain a low THD with constant amplitude if the sine-wave output must remain locked to a ...
