This paper presents an approach to the implementation of systems combining variable gain amplifiers (VGA) and programmable continuous-time G/sub m/-C filters in the video frequency range. The technique relies on the use of a versatile high-performance transconductance amplifier as an active cell. Simulation results from 35 /spl mu/m designs supplied at 3.3… CONTINUE READING
