.. a sudden loss of data or information caused by a power supply disconnection (blackout). Power and voltage spikes, supply frequency changes, noise and radio frequency interference affect negatively the load. In figure, the basic ...
.. to low supply voltages. It could be used as the basis for a PWM control loop, a timer, or a VCO, or as a capacitance-to-frequency converter. It’s a nifty circuit for two reasons: It uses an open-drain comparator output to make ...
.. has required dedicated semiconductor switching devices from both cost and performance standpoints. Although the operating frequency of IGBT is limited to the several tens of kHz due to its inevitably large tail current loss, it is very ...
.. Note CN-0320 December 2013 This circuit is a flexible, frequency agile, direct conversion IF-tobaseband receiver. A fixed conversion gain of 5 dB reduces the cascaded ...
.. inversion in the physical layer before transmission and after reception. With today’s vast selection of radio frequency (RF) transceivers and baseband processors, it is easy to imagine how one could come across a set of RF ...
.. most realize. Take, for example, the smart grid with smart meters. Every day utilities are installing a shiny new smart meter on our house and encouraging us to take control of our energy future. We are to monitor and report consumption ...
.. a trim potentiometer can be added to the midpoint of R2/R3. With the values shown, the pulse-width modulation (PWM) frequency is approximately 45 kHz, which can be modified by changing C3. The power MOSFETs and inductor must be ...
.. of the PCB layers dielectric constant and the proximity to other objects. These parameters affect the actual centre frequency, gain and bandwidth of the antenna. Download Application Note (715 Kb) Efficiency vs. Bandwidth
.. cell is used to power the device and as a light sensor. The output of the described circuit is a square-wave pulse whose frequency is proportional to the light intensity. The circuit does not require a battery to operate and ...
.. Experiments were performed with a single solar cell of diameter D=7.5 cm positioned horizontally on a desk located 1 meter from a window. Although it was sunny outside, practically no direct sunlight passed through the window. Under ...
