Design your own oscillator based on the Wein-bridge configuration. (See Alexander section 10.9.2.) Use one of the two circuits below. Each has a non-linear element (lamp or diodes) to stabilize the circuit. The non-linear element is needed to ensure that the amplification will be exactly three (otherwise, the op-amp output increases to one rail or the other or decays to zero).
