Nyquist-rate analog-to-digital converter specification for Zero-IF UMTS receiver

This paper presents a mathematical analysis method to derive the required specification for an analog-to-digital converter (ADC) to be used in a zero-IF UMTS receiver architecture targeting mobile station application. Wireless standard specifications are used to derive the design plan for a Nyquist converter type. Our research demonstrates that the minimum resolution should be 10 bits for a practical realization that includes design imperfections with the minimum required sampling frequency being 10 MHz.
