Abstract

A GPRS RF solution using sigma-delta modulation and an EDGE RF solution using digital polar modulation are presented. The single-chip, quad-band transceivers have been implemented in a 0.13 μm CMOS technology. The lock-in time of the sigma-delta modulator with integrated loop filter is less than 120 μs with a phase error of 1.2° RMS and an output power of 3.5 dBm; it is fully compliant to the GSM specification. The EDGE transceiver shows a nominal margin of 11 dB to the critical 400 kHz specification with a transmit EVM of 2.5%.
