Analog filter design: Current design techniques and trends

Analog Filters are used in a host of applications and are key building blocks in a number of applications. The main components in active filters are Op Amp (VCVS) or Transconductance Amplifier (VCCS), resistors and capacitors. In this presentation we discuss different implementations of non-conventional Amplifiers and their strengths and weakness. Also we present different non-conventional filter topologies in different domains and/or their implementations. Linearity of amplifiers/filters∗ is still an important active research area, not discussed here for lack of time.
