A High-Linearity, 30 GS/s Track-and-Hold Amplifier and Time Interleaved Sample-and-Hold in an InP-on-CMOS Process

A high-speed, track-and-hold amplifier and interleaved CMOS sample-and-hold circuit are implemented in an InP-on-CMOS fabrication process. Conventional 50- Ω interchip interconnects between III-V and CMOS circuits are eliminated with heterogeneous integration of III-V on CMOS, yielding higher performance circuits at lower power consumption. The track-and-hold amplifier is based on a double-switchi...
