Triangle Wave Oscillators Circuits

10 Hz to 10 Khz VCO With Square and Triangle Wave:

Trans-conductance amp gives oscillator reciprocal response: 04/17/03 EDN-Design Ideas / The circuit in Figure 1 is a variation on the familiar integrator/comparator triangle-wave oscillator, which you typically implement with two op amps. An integrator and a comparator connect in a positive-feedback loop; the comparator drives the integrator and vice versa.
