Abstract :
A fully differential master-slave track-and-hold amplifier is designed and fabricated with a 320-GHz-fT-InP DHBT process. This circuit shows an input bandwidth of 16 GHz and a -3.5 dB forward gain. At 4 GSa/s and for a -4 dBm single-ended input signal, the circuit has a total harmonic distortion lower than -57 dB and -38.6 dB respectively at low frequency and up to 10 GHz. Time domain measurement at 4 GSa/s is also presented.
