Abstract :
A truly modular and power-scalable architecture for low-power programmable frequency dividers is presented. The architecture was used in the realization of a family of low-power fully programmable divider circuits, which consists of a 17-bit UHF divider, an 18-bit L-band divider, and a 12-bit reference divider. Key circuits of the architecture are 2/3 divider cells, which share the same logic and the same circuit implementation. The current consumption of each cell can be determined with a simple power optimization procedure. The implementation of the 2/3 divider cells is presented, the power optimization procedure is described, and the input amplifiers are briefly discussed. The circuits were processed in a standard 0.35 /spl mu/m bulk CMOS technology, and work with a nominal supply voltage of 2.2 V. The power efficiency of the UHF divider is 0.77 GHz/mW, and of the L-band divider, 0.57 GHz/mW. The measured input sensitivity is >10 mV rms for the UHF divider, and >20 mV rms for the L-band divider.
