Future imaging applications in the submillimeter-Wave range (300GHz to 3THz) require RF systems that can achieve high sensitivity and portability at low power consumption levels. In particular, CMOS process technologies are attractive due their price tag for industrial, surveillance, scientific, medical applications. Recently, CMOS-based detectors have shown good up 1THz with NEPs on order of 66pW/√(Hz) [1]. However, terahertz imagers developed thus far only operated single based lock-in...

Abstract This paper studies the problem of state‐feedback stabilization control for a class high order stochastic nonholonomic systems with disturbed virtual directions and more general nonlinear drifts. By using backstepping approach, we develop recursive controller design procedure in setting. To get around burden associated systems, switching strategy is exploited this procedure. The tuning function technique applied to avoid disadvantage overparameterization. It shown that, under some...
