Abstract :
This paper introduces a translinear second-order oscillator that is a direct implementation of a non-linear second-order differential equation. It comprises only two capacitors and a handful of transistors and can be controlled over a very wide frequency range by only one control current. A breadboard version, using transistor arrays, proves the correct operation of the proposed circuit. The oscillator frequency equals 25 kHz, while the total harmonic distortion equals 2.4%
