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...
A fully digital implementation for an RF built-in self-test (RF BIST), incorporated within a digital RF processor (DRPtrade)-based system-on-chip (SoC), is presented. The proposed mechanism serves as an on-chip built-in modulation-noise estimation-module (BIMNEM) for the testing of the 2.4 GHz local oscillator of a Bluetooth transceiver offered by Texas Instruments. This SoC, realized in a standard...
We present the receiver in the first single-chip GSM/GPRS transceiver that incorporates full integration of quad-band receiver, transmitter, memory, power management, dedicated ARM processor and RF built-in self test in a 90-nm digital CMOS process. The architecture uses Nyquist rate direct RF sampling in the receiver and an all-digital phase-locked loop (PLL) for generating the local oscillator (LO)...
