In this paper, we propose a quadrature oscillator-mixer combination. This circuit reuses the bleeding current, which relaxes mixer design trade-offs noise, linearity and gain at low supply voltages, by replacing the bleed current source as an oscillator. The linearized merged oscillator-mixer achieves a 8 dB gain, -4 dBV IIP3 and 6.5 dB white noise figure at the 7 GHz frequency. The phase-noise of...
This paper presents the design and the measurement results of a 3-5-GHz down-converter fabricated in a 90-nm CMOS technology. The circuit consists of a single-ended resistive-feedback low-noise amplifier and two I/Q double-balanced mixers. A transformer-based on-chip single-ended-to-differential conversion allows gain and noise performance to be optimized at a very-low power. A post-layout stability...
A CMOS mixer was design with a new circuit scheme to realize low voltage and high linearity simultaneously. A double balanced Gilbert cell was adopted as the basic topology and TSMC 0.18 mum 1P6M CMOS process was employed for the on-chip RF circuit fabrication. The proposed new circuit scheme consists of LC-tanks as a capacitively coupled resonator for low voltage and multi-stage parallel RC networks...
