Abstract :
The scope of this paper is to evaluate the potential of Sinh filters synthesized by exploiting the exponential V-I relation of weakly inverted MOS devices. We report quiescent power consumption, tunability and linearity simulation results for: (a) a lowpass biquad, (b) a bandpass bi-quad and (c) a third-order Butterworth lowpass CMOS Sinh filter response using the 0.35 μm AMS process parameters. Frey´s state-variable mapping procedure is followed. Key synthesis and performance limitations are identified.
