Tailoring on-chip inductors for low-noise ultra-wide-band receiver applications

Abstract

Inductors have been proven to be an effective on-chip passive element in UWB receiver applications to simultaneously achieve noise and impedance matching. However, the conventional approach of optimizing on-chip inductor quality Q factor for low-GHz narrow-band applications is not appropriate for wideband UWB receiver front-end designs. This is especially severe for applications approaching 10GHz. Suitable inductor dimensions as well as the inductance values need to be carefully chosen to ensure an optimized noise performance and the manufacturability for consumer UWB radio products
