Title
A quadrature relaxation oscillator-mixer in CMOS
Abstract
This paper describes the design of a quadrature cross-coupled oscillator circuit integrated which also realizes the mixer function in a phase lock loop (PLL). This should be able to provide a very accurate phase relation (<1°). This combined oscillator/mixer is first evaluated using a high-level model, in up and downconverter configurations. A circuit implementation is then carried out, in which all the variables are kept independent at circuit level, ensuring a practical implementation close to that of the high-level model. The circuit is designed in a standard 0.35 μm CMOS technology with an oscillation frequency of 900 MHz, it has an overall area of 521 × 515 μm2 (157 × 119 μm2 for the IQ oscillator/mixer circuit) and a power consumption of 70 mW with a 3 V power supply. The circuit performance is evaluated by simulation.
