Examine a traditional Hartley oscillator circuit, and you'll note its trademark: a tapped inductor that determines the frequency of oscillation and provides oscillation-sustaining feedback...

Engineers have long used function- generator circuits employing analog integrators and high-hysteresis comparators. The outputs of these circuits often depend on variations in temperature, power-supply voltage, load, and parts...

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals...

SiTime Corporation introduced an ultra-low-power 32 kHz oscillator family that provides accurate time keeping for advanced driver assistance systems (ADAS), infotainment, instrument clusters and electronic control units...

Wireless connectivity is a growing trend in portable consumer gadgets. Unfortunately, designs cannot achieve true mobility because of short battery life, so the power cord still must connect the device to the power grid to get the required energy or to recharge the batteries...

Digital potentiometers are versatile and can be used in a wide variety of applications, for example, for filtering or generating ac signals. However, sometimes the frequency must be able to be varied and adapted to the desired application...

The circuit works due to the fact that voltage increases or decreases linearly when a constant current flows into or out of a capacitor. If we manage to charge and discharge the capacitor with the same constant current, then the voltage of the capacitor will become a triangular wave...

The EPC9176 GaN-based inverter reference design enhances motor drive system performance, range, precision, torque, all while simplifying design...

Before his name became a brand and a household word, Ray Dolby was a pioneer in noise reduction technology. His innovations revolutionized the audio and entertainment industries...

Known devices for taking the square root contain an operational amplifier and a multiplier connected in a feedback loop. The accuracy of these devices depends on the method of building the multiplier, with the most accurate using logarithm and anti-logarithm functions...
