A fully integrated dual-band offset phase-locked loop (OPLL) for EGSM 900 MHz and DCS 1800 MHz standards is presented. The system is implemented in a 0.35μm SiGe BiCMOS technology with fT of 60 GHz, featuring integrated colpitts VCOs with above-IC thick copper spirals. Simulation results indicate that all EGSM and DCS specifications are met over a temperature range from -20 to 80 °C and power supply range from 2.7 to 3.3 volts. The chip consumes 112 mW and 114 mW in the EGSM and DCS bands respectively.
