This circuit uses simple CMOS logic and two ... Figure 2 shows a 100-MHz square wave input, a 12.5-MHz output for the filter clock, and 1-MHz sine and –cosine square-wave output before the ...

This reference will track the +5 V supply, so that the 50% duty cycle square wave output of the circuit remains at 50% if the supply voltage changes. (The lightly loaded output of the flip-flop also ...

2. The waveforms at four critical points include the output of U1 (the square wave) and the junction of R1 and C1 (the “triangular” wave) (a); the waveforms at R1/C1 and R2/C2 (b); the ...
