This Design Idea avoids the RC charging waveshape of a standard relaxation oscillator, replacing it with a linear rise/fall triangle wave. Positive feedback is used to increase the charging rate over ...
The circuit in Figure 1 seems utterly simple but demonstrates unusual behavior. It produces an almost square wave of odd-integer quartz harmonics, including its main frequency. You can determine the ...
After delving into Texas Instrument’s crystal-replacing bulk acoustic wave (BAW) oscillator recently, Electronics Weekly is taking a look at an advanced version of the humble RC oscillator, reported ...
