Noise and dynamic range of CMOS degenerated active inductor resonators

This paper presents a compensation method of active inductor losses, employing passive gyrator degeneration rather than an external negative impedance converter. Theoretical analysis is confirmed by a comparative simulations of two resonators designed for 434 MHz band, using Eldo RF and Spectre and the UMC 0.18 mum 1P6M process. Presented results show that the proposed loss compensation method achieves comparable noise and large signal performance to a standard active inductor resonator and provides a significant improvement in static power consumption.
