    .. 1 shows a variation on a sine wave oscillator, it uses just two transistors and a single variable resistor to set the frequency. Figure 1. Just a couple of components are needed for a simple tunable sine wave oscillator. The ...

    .. (also called an ultrasonic atomizer), a piezo atomizer disc/transducer (ceramic humidifier) works by transposing high-frequency sound waves into mechanical energy that is transferred into a liquid, creating standing waves. As the ...

    .. the GaN FET. The cascode, shown in Figure 2 consists of an internal switch transistor and the newcomer FET; it has better frequency characteristics than the internal switch alone. So, if the newly added GaN FET also has much lower ...

    .. position, the capacitor has little effect on the signal as long as the RC time constant is long relative to signal frequency and the signal does not go above the diode’s forward voltage. Moving the switch from ...

    .. R S and a 50 nF C X to ground. This capacitor C X will interact with the LTC2063 circuit, resulting in some peaking in the frequency response. This peaking can be used to extend the flat bandwidth of the generator, in much the same way ...

    .. with 10-15% tolerance. Timing capacitors C1-C2 are installed in the header socket (Figure 3), allowing almost the full frequency range of the op amp to be tested if necessary. The capacitors pairs to cover the range of 14 Hz-140 kHz ...

    .. design idea (DI) does exactly that by using asynchronous RS-232 to power and count pulses from a simple 10-kHz voltage-to-frequency converter (VFC). Getting only one bit of info from each 10-bit serial character may seem inefficient ...
