Abstract

An 86.6-dB SFDR, 1-GS/s differential bootstrap sampler in a 0.18-μm SiGe BiCMOS technology is presented. The performance is achieved using an amplitude-modulated bootstrap circuit. The results show 14-bit linearity over nearly 500-MHz bandwidth, while consuming less power compared to a conventional MOSFET switched-capacitor bootstrap circuit due to less parasitic capacitance and the use of high ft HBT.
