Abstract
UWB prescaler operating from 1 GHz to 25 GHz while drawing about 3.5mA from 1.8 V power supply has been designed in 0.18 CMOS process. The prescaler features a new balanced dynamic load technique and an asymmetrical latch structure. The speed enhancement mainly comes from the asymmetrical setting of the D-latch cell, while balanced dynamic load significantly widens the frequency range and at the same time reduces power consumption. The factors and tradeoffs that govern the circuit performances are addressed to optimize the design.
