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...
This paper presents an overview of software aspects of the first-ever single-chip GSM radio realized in 90 nm CMOS. It demonstrates benefits of using highly programmable digital control logic in a wireless SoC system. It also describes a micro-processor design in the digital RF processor (DRP) and how it controls compensation for process, voltage, temperature (PVT) variations of the analog and RF...
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...
Summary form only given. A low key phenomenon received attention only from few technologists. This phenomenon was the ability to reliably scale a CMOS transistor below a certain size, so it could digitally switch at RF frequency rate. This was the birth of "digital RF". This opened new doors to wireless communication implementation - reliably and inexpensively. This article describes the...
We present a system-on-chip (SoC) that integrates a TMS320C54x digital signal processor (DSP), which is commonly used in cellular phones, with a multigigahertz digital RF transmitter that meets the Bluetooth specifications. The RF transmitter is tightly coupled with the DSP and is directly mapped to its address space. The transmitter architecture is based on an all-digital phase-locked loop (ADPLL),...
