This dissertation describes the design of a direct-conversion receiver for third generation mobile communications. Receiver requirements are derived from the respective type approval tests, and receiver immunity to the own transmit signal is identified as a key challenge influencing the receiver planning stage. After a comparison to GSM receiver requirements, issues arising from the choice of the direct-conversion architecture are explained. Key aspects of the baseband part are offset compensation and minimization of settling transients due to programmable gain changes. A thorough analysis of such transients is presented and a minimization strategy is proposed. The description of the actual design of a 0.13m CMOS receiver for UMTS along with its experimental characterization concludes the work.
