Abstract

Although the design of integrated filters using MOS-only circuits provides some vital advantages, these circuits are inherently prone to have limited operating frequency range. This fact leads to a poor tunability range and seriously degrades the usefulness of this class of filters. In order to address this issue, two methods are presented and detailed simulation results verifying the feasibility of the techniques are provided.
