What's the Difference Between a Tuned and an Untuned Oscillator Circuit?
Ditulis pada: September 29, 2018
A tuned oscillator uses a LC (inductor-capacitor) tank-circuit, a frequency-selective RC (resistor-capacitor) circuit or a quartz crystal circuit in its feedback path. Generally, the output waveform shape from a tuned oscillator circuit is sinusoidal and for this to positive feedback is used around an amplifying device such as a transistor or op-amp. If negative feedback …
