We present two RF frequency dissemination methods (active and passive phase fluctuation compensation) for branching network. For the active one, the phase noise compensation function placed at the client site. One transmitting module hence can be linked with multiple client sites. For the passive one, without any phase control on the disseminated rf signals or usages of active feedback loop, the highly...
The design of a 14-mW receiver without phase-locked loop for the Chinese electronic toll collection (ETC) system in a standard 0.18- $\mu\hbox{m}$ CMOS process is presented in this brief. Since the previously published work was mainly based on vehicle-powered systems, low power consumption was not the primary goal of such a system. In contrast, the presented system is designed for a battery-powered...
A wideband 3.5 to 5.5GHz low voltage folded-switching mixer is implemented in 0.25um SOI CMOS technology. The post-layout simulation of the designed mixer at 4.5GHz has noise figure (NF) of 9.6dB, input IP3 of −9dBm, conversion gain (CG) of 10.9dB and total current consumption including bias is 4.5mA under 1.5V supply voltage. The designed mixer can also operate under 1V supply voltage with relatively...
