A technique to reduce the Phase Noise of a Quadrature Differential Oscillator is described. The technique uses inverters to shape the tail noise of differential oscillators. In this approach an inverter is used to increase the ldquosquarenessrdquo of the switching signal from the differential output and thereby improve the switching speed. Simulations are done to obtain the results to verify the new...
CMOS technology scaling trends and power requirements demand circuits which operate at lower supply voltages. However threshold voltage scaling doesn't exactly follow supply voltage scaling. Therefore circuit techniques like current-mode circuits, which are less sensitive to supply voltage level, are required. In this direction and in the context of mixed-signal design this paper presents two 6-bit...
This paper presents a new technique for Low-Phase Noise CMOS Quadrature differential oscillator with better phase noise. The design uses tail noise shaping along with Gm3 boosting circuit and third harmonic tuned LC tank for improved phase noise performance. The proposed quadrature oscillator circuit shows a 4 dB phase noise improvement over standard fixed bias quadrature oscillator. Post Layout Simulation...
