A compact, high linearity 40GS/s track-and-hold amplifier in 90nm SiGe technology


The design of low distortion, high speed transceivers requires high performance Track and Hold Amplifier (THA) front ends to Analog to Digital Converters. This paper reports the design and characterization of a highly linear THA fabricated in 90nm SiGe Heterojunction Bipolar Transistor technology with Effective Number of Bits>4.9. Improved linearity is… (More)
