Abstract
A fifth-order elliptic low-pass continuous-time filter based on triode transconductors for applications in the video frequency range is presented. Fabricated in a standard 2- mu m CMOS technology, the circuit occupies 6 mm/sup 2/ of silicon area including the automatic tuning circuitry. The filter achieves a 7-MHz cutoff frequency using a parasitic pole compensation scheme. The dynamic range is 40 dB and power consumption is 30 mW for a 5-V supply. A transconductor biasing strategy which allows a continuous tuning range for the cutoff frequency of one decade is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
