70 GHz Large-signal Bandwidth Sampler Using Current-mode Integrate-and-Hold Circuit in 130 nm SiGe BiCMOS Technology

This paper presents a broadband sampler IC using a current-mode integrated-and-hold-circuit (IHC) as sampling circuit. The sampler IC exhibits 1dB large-signal bandwidth of 70 GHz and excellent signal integrity on hold-mode. With a sampling rate of 5 GS/s, it achieves effective number of bits (ENOB) of 6 bit at 9.9 GHz input frequency. The chip was fabricated in a 130 nm SiGe BiCMOS technology from IHP.
