Figure 1 shows the result. Figure 1 Kibitzer’s version of a McLucas frequency multiplier and square wave generator. Figure 1’s circuit comprises two almost identical sections: input processor, IP ...

Here is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are similar circuits in the literature [References 1, 2, 3] which require ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed.
