This paper presents a 77GHz, 16dBm, 13% PAE power amplifier. It is simulated in a 0.13um silicon-germanium technology with fT of 200GHz. The design technique is not the same as those which are used in traditional power amplifiers. All the matching structures are composed of short or open stubs and MIM capacitors. To get a higher output saturation power, breakdown voltage is also considered in bias...
Despite of the popularity of activity-based travel behavior analysis, there is few studies taking the other peoples' travel behavior from neighboring household into model specification, and the effects of the socio-demographic and environmental determinants on different members in the same household are ignored. Using the data from 2013 Nanjing Resident Travel Survey, this paper applied the spatial...
We report three experiments on manual detection of torque variations experienced through a rotary switch. The experiments were designed to investigate whether torque perception was determined by the spatial or by the temporal characteristics of the rotary switch. In Exp. I, manual detection thresholds of torque variation were measured with raised sinusoidal torque profiles that varied in spatial period...
