ABSTRACT:
A transconductor-C filter that has coarse and fine control mechanisms allowing for both high speed and high current filtering of the same signal. The filter uses a current controlled oscillator and filter elements that have switchable amplification devices enabling the circuit to adapt to external and internal conditions in real-time. An equalizer is described utilizing the transconductor-C element. Finally, a Phase Locked Loop for providing the control signals to the transconductor-C element is also described.
