This lecture covers different types of continuous-time filters (CTFs), focusing on MOSFET-C filters. It explains the operation of Gm-C filters and pseudo-differential Gm-C filters. The linearization techniques based on overdrive voltage and resistive degeneration are discussed. The Krummenacher differential pair principle is presented, along with its applications in strong and weak inversion. The lecture also explores the multi-tanh linearization principle and the linear model of operational transconductance amplifiers (OTAs). Source-follower continuous-time filters are introduced, emphasizing low-power analog IC design.
