Abstract

Novel BiCMOS sinh-domain filter topologies, derived according to operational emulation and component substitution techniques of the corresponding passive prototype filters, are introduced in this paper. This has been achieved by utilizing BiCMOS nonlinear transconductor cells and an appropriate set of complementary operators for transposing the corresponding equations into the sinh domain. An attractive benefit of the proposed filter topologies is their capability for operating in a low-voltage environment. The performance of a leapfrog sinh-domain filter has been compared, using the Analog Design Environment of the Cadence software, with those of the corresponding log-domain and operational transconductance amplifier (OTA)-C filters.
