An LC oscillator is a circuit we use to turn a DC supply into an AC output waveform. So now this output can show many waveform shapes and many frequencies, […]
Wien Bridge Oscillator Circuit Explained with Calculations
We remember this thing from the RC Oscillator tutorial, where resistors and capacitors are connected together with an inverting amplifier, and somehow that setup starts oscillating on its own. From […]
