conference paper Liang Wu author 30401 Maxim Weizel author 44271https://orcid.org/0000-0003-2699-9839 Christoph Scheytt author 371440000-0002-5950-6618 58 department This paper presents a broadband track-and-hold amplifier (THA) based on switched-emitter-follower (SEF) topology. The THA exhibits a record 3dB small-signal bandwidth of 70 GHz. With the high sampling rate of 40 GS/s, it achieves an effective number of bits (ENOB) of 7.5 bit at 1 GHz input frequency and an ENOB of >5 bit up to 15 GHz input frequency. The chip was fabricated in a 130 nm SiGe BiCMOS technology from IHP (SG13G2). It draws 110 mA from a -4 V supply voltage, dissipating 440 mW. 2019 eng 10.1109/ICECS46596.2019.8965046 Wu L, Weizel M, Scheytt C.
