This paper presents a digitalized gyroscope system using ΣΔ modulation on ADC (Analog to Digital Converter) and DAC (Digital to Analog Converter) sections. Both discrete ADC and DAC chips are replaced with these ΣΔ sections. The ΣΔ ADC technology can convert signals between analog and digital domain...
