Here, a self-oscillating mixer is experimentally demonstrated employing both the fundamental and harmonic signals generated by the oscillator sub-circuit in the mixing process. The resulting circuit is a dual-band down-converting mixer that can operate in the C-band, or in the X-band. The oscillator uses the active super harmonic coupling to enforce the quadrature relationship of […]
The purpose of this study is to investigate microelectromechanical behavior of smart piezoelectric actuators using Artificial Neural Networks due to simple, multi harmonic and dynamic pulse excitations. Regarding to complexity and time-consuming analyses of vibration of smart structures, existing classical models are often insufficient. Nowadays, artificial intelligence tools are used for modeling such complex phenomena. […]
In this paper, a Distributed Amplifier (DA) by using HEMT technology for ultra-wideband application is presented. Creation of Distributed integrated circuit has been investigated for approximately seventy years rapidly to developing semiconductor process technologies in the modern IC design. By using of this method, multiple parallel signals are combined and obtain to increase the bandwidth, […]
