Abstract

This paper presents a switched capacitor voltage doubler as analog signal amplifier to increase the swing in low voltage electronics like PLLs. A signal is doubled with respect to a reference voltage which results in a wide signal swing exceeding the supply rails. An analytical expression of the transfer function, from which design equations for circuit parameters can be obtained, is derived including the effect of incomplete voltage settling due to finite switch resistances. The theory is validated by measurements of a voltage doubler as part of a PLL charge pump in 90nm CMOS technology.
