Abstract

A highly selective frequency filter is created from lossy components such as found in standard integrated circuit technologies, including particularly CMOS technologies, without the use of active loss cancellation circuitry. The filter configuration is based on using inductively coupled planar inductors for introducing a mutual inductance factor that advantageously alters the frequency response of the filter.
