Active filter tuned oscillator

Clean textbook circuit schematic of an active-filter-tuned analog oscillator drawn with standard black schematic symbols. The circuit is built around an op-amp or paired op-amp amplifier section integrated with an active RC filter network that sets the oscillation frequency. Show resistors and capacitors arranged in the filter and feedback paths, with a recognizable oscillator loop and output node. Include two op-amp triangles, RC filter elements, and a diode limiter network in the feedback path. Overall style should be neat, reusable, and clearly schematic rather than pictorial.
