VHDL-AMS in switched-current analog filter pair design based on a gyrator-capacitor prototype circuit

Abstract

This paper presents an approach to a low-sensitivity design strategy for switched-current (SI) filter pairs based on a gyrator-capacitor prototype circuit. On the basis of a prototype filter, an SI counterpart circuit is obtained. Tools for SI filter design automation have been developed, which make a hardware description language - analog-mixed signal synthesization for the chosen kind of circuit. The obtained SI filter is better than the filter obtained using LC ladder structures with respect to very-large-scale integration complementary metal-oxide-semiconductor chip area and power consumption.
