Abstract :
A 15/16 dual-modulus prescaler suitable for multi-band transceivers and implemented using an Adaptable MOS Current Mode Logic (AMCML) family is described. The AMCML circuits allow the drive current and voltage swing of the logic gates to be adaptively controlled, enabling real-time adaptation to achieve an optimum balance between power, speed, and robustness. The prescaler was designed in a mixed-signal TSMC 0.18 μm CMOS process and requires between 150 μA and 1 mA of current for operation over the 800 MHz to 3 GHz frequency range, from a 1.8 V supply.
