Abstract

The active inductor (AI) is a promising strategy for use in analog receiver filters applied to aerospace devices, as it occupies a smaller silicon area. This paper presents the preliminary design of an AI implemented in a 65-nm CMOS process, which obtained an L of 14.97~nH with a quality factor of 3.7. It was employed to implement an L-C band-pass filter at 401.5~MHz intended for small-satellite RF receivers.
