摘要：

This paper presents a low-power high-speed BiCMOS track-and-hold amplifier (THA). It combines the differential switched-emitter follower of [1] with the low-droop output buffer presented in [2]. A test implementation consumes 70mW of total power (30 mW THA). It works up to 15 GS/s, using minimum-size HBTs in a 0.25 mu m 200 GHz SiGe BiCMOS technology. At 10 GS/s and an input signal of I GHz, the achieved THD corresponds to 6.8 bits accuracy. To our knowledge, the present circuit is by far the fastest THA with low power consumption and high accuracy.
