  text: 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.
