How to use op amps with a single rail power supply?
Method #1: Voltage divider using two resistors. Method #2: Voltage divider using two Zener diodes.
Wien-bridge Oscillator with Op Amp
The Wien-bridge oscillator, consists of an Operational Amplifier (OA) in a non-inverting configuration with gain 1+R2/R1 and a RC feedback network
Nonlinear Amplitude Control of a Sinusoidal Oscillator
Control of a sinusoidal oscillator is done in 2 phases: a linear method based in the frequency domain and a non-linear method using non linear mechanisms
