A 6 GHz 60 mW BiCMOS phase-locked loop with 2 V supply

Abstract

The 6 GHz phase-locked loop (PLL) in a 20 GHz BiCMOS presented in this paper requires no external components and dissipates 60 mW, a factor of 13 less than the circuit in a 22 GHz HBT technology reported by Buchwald et. al. (1992). Low-voltage techniques allow the PLL to operate with supply voltages as low as 2 V.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
