This paper presents the IC design of a low power, wide tuning range and low phase noise voltage-controlled oscillator (VCO) in a standard 90-nm CMOS technology. The newly proposed current-reuse cross-connected pair is utilized as a negative conductance generator to compensate the energy loss of the resonator. The supply current is reduced by half compared… (More)
In this paper, a broadband planar array at Ku band is designed and manufactured, which is comprised of 48times48 annular slot elements. From calculated and experimental results, the obtained impedance bandwidth (VSWR<2) reach 20.56%, the gain reach 34.5 dB. The proposed planar array satisfies the use of satellite communications.
