Our hacker [Wil Carver] has sent in his submission for the One Hertz Challenge: Precise Time Ref via 1 Pulse-Per-Second GPS Signal. This GPS Disciplined Oscillator (GPSDO) project uses a Piezo 2940210 ...

A phase-locked loop (PLL) is a feedback system that combines a voltage-controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or ...

Voltage-controlled oscillators (VCOs) have a difficult challenge. On one side, they need to be stable with low values of detrimental characteristics such as phase noise, jitter, and drift. On the ...

Oscillators are critical components in aerospace and defense systems, ranging from communication satellites to portable tactical radios and from ground-based RADAR to the GPS systems in smart ...

Sawtooth- or exponential-ramp relaxation oscillators are common and generally easy to build. However sometimes a cleaner waveform is desired, and generators of even-symmetric waveforms are a bit more ...

Editor’s Note: This DI is a two-part series. Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher ...

Researchers have modeled how the combination of a virtual oscillator control mechanism and a cascaded sliding mode control can help regulate voltage and frequency in a distributed-solar microgrid.
