Abstract :
In this paper, we present a novel voltage follower topology, developed both in bipolar and in CMOS standard technologies. The buffers works at low supply voltages (±1 V for bipolar and ±0.75 V for CMOS) and have improved performance in terms of rail-to-rail input and output characteristics and low quiescent power consumption. The slew rate is very high if compared with other solutions presented in the literature. The determination of the efficiency factor, defined as GBW(MHz)*Cload(pF)/Power(mW), shows that our solutions are much better than the other topologies proposed in the literature
