Abstract :
A 1.2V 42mA all-digital PLL and polar transmitter for a single-chip GSM/EDGE transceiver is implemented in 90nm CMOS. It transmits GMSK with 0.5° rms phase error and achieves -165dBc/Hz phase noise at 20MHz offset, with 10 μs settling time. A digitally controlled 6dBm class-E PA modulates the amplitude and meets the EDGE spectral mask with 3.5% EVM.
