Abstract

This paper presents a high-accuracy, low-drift 16 MHz RC frequency reference. It is based on a Wien bridge filter that incorporates silicided n-poly resistors and MIM capacitors, whose temperature coefficient is compensated by a PNP-based temperature sensor. After a 2-point trim, it achieves ± 350 ppm inaccuracy from -45°C to 85° C, which increases to only ± 450 ppm after accelerated aging. This represents competitive accuracy and state-of-the-art stability for RC-based frequency references, approaching that of their LC-based counterparts while dissipating lower power and occupying less area.
