A 3.1-10.6 GHz ultra-wideband (UWB) low noise amplifier (LNA) utilizing a current-reused technique and a simple high-pass input matching network is proposed. The implemented LNA presents a maximum power gain of 16 dB, and a good input matching of 50 in the required band. An excellent noise figure (NF) of 3.1-6 dB was obtained in the frequency range of 3.1-10.6 GHz with a power dissipation of 11.9 mW under a 1.8-V power supply. The proposed UWB LNA demonstrates the highest power gain and lowest NF among the published works in 0.18-m CMOS technology.

Abstract. In this paper, we study the existence and uniqueness of solutions to stochastic differential equations driven by G-Brownian motion (GSDEs) with integral-Lipschitz conditions on their coefficients.

Abstract. This paper studies the solvability and the stability of stochastic differential equations driven by G-Brownian motion (GSDEs). In particular, the existence and uniqueness of the solution for locally Lipschitz GSDEs is obtained by localization methods, also the stability of such GSDEs are discussed with Lyapunov-type conditions.
