RF design has matured to the point where almost any wireless standard (e.g., GSM, WiFi, Bluetooth, etc.) and/or multiple standards operating in different bands can be integrated onto a single chip in deep submicron CMOS. This course is an in-depth tutorial that discusses many of the challenges facing the designer of a single-chip radio, and their solutions. The topics addressed in the course range...
In the last few years cellular market well exceeded 1.3B cellular mobile devices shipped per year. The ongoing economic-driven shrink in technology towards nanoscale CMOS enables increased functionality in even smaller silicon area, however, technology effects including process variation, variability, temperature effects, flicker noise etc. put stringent challenges on the design and have significant...
A self-calibrated two-point delta-sigma modulation technique for CMOS RF transmitter is proposed. This calibration technique employs voltage-controlled oscillator (VCO) and delta-sigma modulator input ports in a frequency synthesizer. By monitoring the control voltage of a loop filter, the gain mismatch between two paths can be detected and completely calibrated by modifying the gain of the VCO path...
A low-noise EDGE transmitter implemented in a 65nm CMOS process using direct-conversion architecture for low-band application is presented. The transmitter consists of a programmable-gain I/Q modulator, a frequency divider and a power detector for carrier leakage calibration. The design delivers maximum output power > 1.5 dBm with a 0.5 dB gain step for the 30 dB dynamic range and has < -68...
