What type of oscillators use resistors and capacitors to form their frequency-determining networks?

RC oscillators utilize resistors and capacitors to create their frequency-determining networks. In these types of circuits, the combination of resistance and capacitance creates an electrical network that can produce a sinusoidal output signal at a specific frequency. The frequency is primarily determined by the RC time constant, which is the product of resistance and capacitance.

In contrast, LC oscillators rely on inductors and capacitors to set their oscillation frequency, while crystal oscillators use quartz crystals to achieve highly stable frequencies. Phase-shift oscillators employ a series of RC networks to produce phase shifts, but they are typically classified under a broader category of RC oscillators rather than as a singular type on their own. Thus, RC oscillators remain the correct classification for those using resistors and capacitors to establish their operational frequency.
