  • Abstract
    An analog sinusoidal oscillator usually involves some form of amplitude-limiting mechanism. We examine OTA nonlinearity as a choice for amplitude limiting, and introduce a general method for its use in OTA-C oscillators. We illustrate our discussion with an example design that we fabricated and tested. Our results show that OTA nonlinearity yields low-distortion oscillators at practically no power- or area cost
