Abstract :
The paper presents an implementation of continuous time analog filter dedicated for nonuniform sampling delta modulator (NSDM) based audio codec. The circuit is also suited for low voltage application-it is based on CMOS inverter working in weak inversion region. System considerations, filter synthesis as well as simulation results of the chip sent for manufacturing are presented.
