Development of backing piezoelectric micromachined ultrasonic transducer (B-PMUT) 2D array

Xu-Bo Wang, You-Cao Ma, Le-Ming He, Yan Wang, Wei-Jiang Xu, Antoine Riaud, Jun-Yan Ren, Jia Zhou

To improve the problem of narrow bandwidth and large crosstalk in high-frequency PMUT array, a PMUT device with a damping backing structure (B-PMUT) is proposed and realized. The device is a two-dimensional array of 8×16 elements with an element pitch of 75 µm. The results show that the bandwidth...

75 nm gate length PHEMT with f max = 800 GHz using asymmetric gate recess: RF and noise investigation

M. Samnouni, Nicolas Wichmann, X. Wallart, Christophe Coinon, Sylvie Lepilliet, S. Bollaert

We report a high maximum frequency of oscillation (f max) and a current-gain cutoff frequency (f T) of 800 and 260 GHz, respectively, with pseudomorphic high-electron mobility transistor (PHEMT), using an InGaAs/InAs composite channel and an asymmetric gate recess. This result was achieved with...
