This paper presents a low power wideband receiver front-end implemented in 0.18 um CMOS technology for LTE application. The front-end includes a low-noise amplifier and a quadrature passive current commutating mixer. The inductive peaking LNA is designed using common gate topology for wideband matching with low power consumption. A noise cancellation technique is adopted for the LNA to achieve NF...
This paper presents an alternative topology for realizing a four-quadrant amplifier with single-ended output. In the proposed multiplier, constituting differential circuits are vertically arranged resulting in single-ended current output with output DC voltage equal to a half of supply voltage. Since the circuit operates in a current-reused mode, the power consumption is systematically reduced by...
An LC-VCO with halt of the power dissipation of a that of the conventional topology is presented. The LC-VCO replaces one of the NMOSFET of the conventional differential LC-VCO with a PMOSFET. The operational principles and design guidelines of the proposed topology are reported. The proposed LC-VCO is implemented in a 0.18 /spl mu/m CMOS technology for 2GHz applications and measurements show phase...
