Abstract

A novel tuning principle for simple gyrator-based CMOS active inductor (AI) circuit is presented. The method makes use of Widlar current source to enhance the quality factor. The simulation of the proposed AI provides a maximum quality factor of 1819 at 2.88[Formula: see text]GHz. The AI shows the inductive bandwidth of 1.66[Formula: see text]GHz to 3.16[Formula: see text]GHz and power consumption of 6.87[Formula: see text]mW. The other characterization factors such as linearity, supply voltage sensitivity and noise analysis are discussed. The performance of the tunable AI using Widlar current source are compared with the same using a simple current mirror. An AI using a conventional current mirror (CCM) and Widlar current source have been implemented in the 0.18[Formula: see text][Formula: see text]m CMOS technology.
