Zusammenfassung: | Differential amplifiers incorporating the advantages of both Si and III-V technologies have been fabricated in a wafer scale, heterogeneously integrated, process using both 250 nm InP DHBTs and 130 nm CMOS. These ICs demonstrated gain-bandwidth product of 40-130 GHz and low frequency gain > 45 dB . The use of InP DHBTs supports a > 6.9 V differential output swing and a slew rate > 4 times 10 4 V/mus to be achieved with as low as 40 mW dissipated power. A novel on-chip buffer circuit is used to facilitate the on-wafer characterization of these amplifiers. To the authors' knowledge, this is the first demonstration of a high performance IC building block in a heterogeneously integrated process technology. |
