This paper describes a 2.7-V dual modulus (divided by 64/65, divided b
y 128/129) prescaler that operates up to 1.5 GHz with a power consumpt
ion of 1.97 mW (Vcc = 2.3 V, Icc = 860 mu A). The;prescaler also incor
porates a stand-by mode feature, which reduces its power dissipation t
o 0.12 mW when enabled. This performance has been achieved on a 0.8-mu
m advanced bipolar technology.
