Abstract :
This paper presents a divide-by-64 low power prescaler operating up to GHz frequency. By adopting the stacked structure circuits, the power consumption of the prescaler has been reduced to 3.8mW (@5v power supply, 1.2GHz). Moreover, the layout area is also reduced to 0.47mm2 through this structure. In this paper, this circuit is applied in the PLL of an ASK receiver which operates at ISM band from 290MHz to 460MHz. Simulated with Hspice and Cadence Spectre, the circuit is implemented at a 0 8μm BiCMOS process.
