.. via R 2 . Figure 1 shows that the µC converts period T into a number by filling the period with clock pulses of frequency f CLK = 1 MHz. It also adds 50 to the result to cancel the offset. The range of the obtained numbers is ...
.. topologies abound for converting current to voltage, voltage to current, voltage to frequency, and frequency to voltage, among other conversions. Figure 1 joins the flock while singing a somewhat ...
.. designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation. Figure 1. A digital frequency divider circuit that ...
.. of 3×10 12 . Unfortunately, upgrading an existing application from a basic crystal clock to a high stability frequency reference is not a straightforward task. This is because these high-precision sources operate at a ...
.. want to scale the capacitors’ values for some other reason, even if the resistors are unchanged. Changing the PWM frequency by a factor F will change the ripple amplitude by a factor of F 3 . But too high a frequency could ...
.. 2, show simultaneous-sequencing results. Significantly, in this implementation both converters run at the same switching frequency. IC 2 is the master controller, programmed to a 700-kHz switching frequency. IC 1 starts at a lower ...
.. proportional to C4. So, if you need more resolution, simply decrease C4 to gain gain. Note that the U1aU2a clock’s frequency precision and stability is somewhat dubious (even if we’re charitable). Happily, the accuracy of ...
.. bipolar transistors or low current op Amps, often require more current than necessary. The circuit shown generates a low frequency square wave signal while drawing only 0.5 microamps from a 6 volt supply. The circuit uses a number of ...
.. pulses. In this case, the accuracy estimate of the high-voltage pulse is better than 0.5% at 25 kV. The free-running frequency of the converter depends on the time it takes to lead Q 1 out of saturation (first part of the cycle) ...
