In this paper we present a quad-band single-chip GSM/GPRS radio in 90 nm digital CMOS process based on the digital RF Processor (DRPtrade) technology. This chip integrates all functions from physical layer to the protocol stack and peripheral support in a single chip RF SoC. The transmitter uses a low-area small-signal digital polar architecture merging amplitude and phase information directly in...
We present a novel approach for built-in self-testing (BIST) of an RF wireless transmitter. This approach, based on fully-digital hardware and on software algorithms, allows the testing of the transmitter's analog/RF circuitry while providing low-cost replacements for the costly traditional RF tests. The testing approach is structural in nature and substitutes for the commonly employed RF performance...
