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 ...

While sinusoid signal sources are used whenever low phase noise is required, conversion to a square wave-form is necessary when interfacing with digital circuits. Although have been analyzed a few ...

This paper describes a theoretical analysis of sine-to-square conversion when noise is included in the conversion process. The analysis is done for conversion performed by a comparator. As a result of ...
