Sine Wave Oscillator: Possible Designs

A project log for ESR and Capacitance Meter

A practical capacitor meter that can simultaneously measure the equivalent series resistance and the capacitance of a capacitor in-circuit.

The first component of the meter is a sine wave oscillator. There are several ways to generate a sine wave; the most common are:

I've found the following references particularly useful:

Right now I'm currently evaluating the different oscillators, mostly based on price and distortion.
