Abstract

The design of an nMOS relaxation oscillator with an operating frequency of 60-250 MHz is presented. The design can be incorporated in a PLL system with centre frequency up to 190 MHz. The oscillator gives a highly linear voltage-frequency characteristic and its temperature coefficient is maintained within ±200 ppm for temperatures ranging from 0 to 80°C. The design was found to be suitable in PLL system applications.
