Abstract :
A fully differential 40 Gsample/s Track and Hold Amplifier with High Dynamic and Large Bandwidth is designed and fabricated in 210 GHz-fT-InP-DHBT process. Spectral measurements in track mode give a THD and a SFDR of -42.5 dB and -43.8 dB respectively for input frequency up to 9 GHz and input voltage up to -2 dBm. This THD is equivalent to 6.7 ENOB. 40 GHz sampling with 2 GHz sinusoidal input signals were measured.
