Voltage comparators began appearing in single-chip microcontrollers (MCUs) in the late 1990s. At the time, the change was viewed as a simple cost reduction. Comparators required less silicon, while ...

where f O is the oscillation frequency.With a suitable choice of the valuesof inductors and capacitors, the circuitcan oscillate at frequencies as high as10 MHz. The output clock’s duty cycle ...

So, you have selected an MCU with an analog-to-digital converter (ADC) and analog comparator peripherals for your cost-sensitive application. You then realize that your sensor signal needs to be ...

If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...

The linearity of triangular waveforms makes triangular wave generators useful in many “sweep” circuits and test equipment. For example, switched-mode power supplies and induction motor-control ...
